Nickel Grain Analysis from Alexander Parkhomov

There have been a number of people who have been wanting to know about the size and shape of the grains of nickel powder used in Alexander Parkhomov’s ‘Hot Cat’ replication attempt. I asked Mr. Parkhamov about this, also about what his future plans were for continued testing were, and whether he had considered using iron (as was found in the fuel used in the Lugano test of Andrea Rossi’s Hot Cat).

His response:

In the appendix outcomes of sizes analysis of the used nickel powder. My next problem – to achieve long duration steady activity of the reactor. In the component of iron I do not see yet necessity.

This is the document he provided of the nickel powder analysis:


  • Gerard McEk

    It looks like a serious study of the material, good! Alexanders reply indicates he continues the tests, good!
    Frank, do you know if he reads ECW?

    • ecatworld

      I don’t know, but I invited him to join us hear and comment if he wanted. He says his English is not so good, so that may be a bit of a challenge.

      • Sean

        Tell him to use Google translator. Easy. Just copy from ecatworld cntrl A then paste cntl v to the google translate page. Possibly you can put a link to google translate on your web site.

        • Josh G

          Two easier translation methods: You can also just copy the URL into google translate and it will translate the page. And if you use Chrome as your browser, you can just ‘right-click’ the mouse anywhere the page you’re on and there is an option to translate.

          But adding a widget to the site for translation is a good suggestion and should be easy to implement. They are also easy to get from google translate.

      • NT

        From what he has written so far, I get the meaning and context very well – tell him to go ahead and join the group. We all make grammar mistakes and understand the problem…

  • Mats002

    The new input from Parkhomov is so cool, it is popcorn-time again!

  • Mr. Moho

    It doesn’t look like the nickel powder used has a large (catalytic) specific surface area either.

    • Andreas Moraitis

      The size of the particles appears to be the decisive factor. If SPP/LSP theory is correct, it should be compatible with the IR wavelength of the stimulating heat source. Perhaps the variability of sizes in this powder is an advantage, since it might work in a wider temperature range.

      • Gerard McEk

        1200 C should than have grains less than 2 um? (Vaporised lithium requires a temperature of 1342 C. Melted lithium 180 degrees, I am not sur what is required). 4 um grains should than be optimal for 454 C. If that theory is true, than Alexander should make the grains smaller. I assume that the process works better at high temperature or is that not related?

        • Andreas Moraitis

          I think your numbers are correct. WolframAlpha gives a blackbody peak wavelength of 1967 nm at 1200C and 3985 nm at 454C:

          However, since the radiation is not monochromatic there will be a certain leeway. But this model could explain the paradox that Rossi needs a thermal input in order to control an exothermic reaction. If he increases the heater temperature until the dominant wavelengths are shorter than the particle size, the reaction will presumably cease.

      • Mr. Moho

        Good point about particle size distribution. Some micropowder manufacturers do provide these data too. It could be important.

      • Mats002

        I stick out my neck and say the grain size and other properties of Nickel (except that there are a few isotopes not working) is not of critical importance because:

        Axil Axil here on ECW :

        The “secret sauce” is an alkali metal like lithium or potassium: an element with a low vaporization point that first vaporizes and then re-condenses into Rydberg matter after each input heat pulse. These nanoparticles will eventually sinter but will always be renewed to provide a constant resupply of fresh nanopowder in a dynamic process.

        Piantelli patent EP2368252B1 at paragraph 0039 about the same said process:

        “Alternatively, the process of depositing [the transition metal] can be performed by means of an epitaxial deposition, in which the deposit attains a crystalline structure that is similar to the structure of the substrate, thus allowing the control of such parameters.”

        My understanding: The 10% of Li[AlH4] used by Parkhomov is [the transition metal] which because of input heat will evaporate and form small nano-clusters on to the substrate which is the Nickel micropowder grains.

        More from Piantelli patent EP2368252B1 at paragraph 0016 about what is happening next:

        “The micro/nanometric clusters structure is a requirement for producing H- ions and for the above cited orbital and nuclear capture processes.”

        If Nickel grain size matters, why is Parkhomov so successful with the described variance? The goal is to form NAE:s which is much smaller than the Nickel grains.

        But I have another question: Where are H-atoms coming from? Is it evaporated from the Li[AlH4] because I can’t find anything about adding H2-gas in the descriptions from Parkhomov.

        I recommend reading Piantellis patent, he covers a lot of ground, and to my understanding he include the inner workings of the E-Cat as described above. If so Rossi/IH must have something even better to get IP protection.

        • Andreas Moraitis

          It could well be that both the properties of the nickel grains and the lithium drops are important. Maybe it will take decades of research until we know exactly how it works.

          The hydrogen results from decomposition of the LiAlH4, as described on slide 9 of the Parkhomov report.

          • Mats002

            Thanks Andreas and you might be right about the properties of the ingredients but if so why is Parkhomov successful with – as it seems – such a little effort? @Frank: Can you ask about this?

          • Bob Greenyer

            To be fair, he is an accomplished scientist and used a method of calorimetry that was honed by one of the most experienced Russian LENR researchers Yuri Bazhutov.

        • tlp

          Randell Mills has patented (or an application?) LiAlH4 + Ni as a hydrogen dissociator run at elevated temperature.

  • Mike Ivanov

    Nice. I think it should be enough to reproduce the experiment by any concerned researcher 🙂

  • Bob Greenyer

    Thanks again Alexander,

    This is excellent detail and we have powders across this range in stock. I think we will go for the

    2.2-2.6um nickel powder (Vale Ni T255) as this in the middle of the range.

    As this has pyramidal features of far smaller size and a filament structure also.

    • Guest

      Very symbolic picture, actually 🙂

    • Mats002

      75 Kg should be enough :-). But this powder lack the variance in sizes, you seems to bet on smaller grains with little variance? A tip from Piantelli?

      • Mike Ivanov

        Do you know how much do they charge for the barrel?

        • Mats002
          • Mike Ivanov

            After Parkhomov experiment I start thinking to build home heater based on this design, for personal usage. Heating is very expensive in Canada….

          • Mats002

            Yes why not? I hope Rossi/IH will be very successful with industry but in the mean time garage tinkerers might be setting the stage for domestic use. My concern is safety. Some parts might better be prepared by professionals.

          • Mike Ivanov

            It could be already a good time for smart entrepreneur to start selling DIY kits online. heating wires, ceramic pipes, Hi, Li, etc – nothing special so far.

          • Mats002

            MFMP are in a very good position to do just that. After a successful replication they can finance their upcoming Live Open Science projects by selling replication kits. I am in line to buy (I hope). First thing first though.

          • Axil Axil

            Before you start, get yourself a good gamma ray detector. Remember that you are building a nuclear reactor.

          • Mike Ivanov

            So far none of independent researches ever confirm any radiation during the process. It is all by words Mr. Rossi only.

            And, to avoid any bad analogies, nobody should call these things “nuclear reactors” or like this. There are two basic types real nuclear reactors in a world, running uranium and plutonium. Any other devices are NOT nuclear reactors, lets keep it like this. Nobody want to fall under regulations for nuclear materials, etc.

          • Jostein Johansen

            Thank you to Dr. Parkhomov . On a completely different note, Nickel is the best performing metal when it comes to price in 2014 according to this chart. , with palladium in second spot. Coincidence?

    • Pekka Janhunen

      If you have several size powders available, why not mix them together to mimic what Parkhomov had. Because there is no guarantee that the effective size is in the middle of his range. Parkhomov probably used a wide range distribution to increase the likelihood that the effect is found. Also, his mass of fuel per reactor volume is about 10 times greater than Lugano. That is also consistent with the idea that only part of Parkhomov’s powder was actually doing something.

      • Bob Greenyer

        We have considered that, but the material we have chosen is in a sweet spot for the target temperature and has features of much smaller scale on it. It is also affordable as a start point for further study.

        We have 3 cores and so can fast cycle (assuming the first one does not take the Dog Bone out)

    • Gerard McEk

      Bob, I read this dialogue between Rossi and Steven Karels on the JoNP blog. (see below)
      Are you aware of these pressures and maybe the omission of the ‘Catalyst’?
      (Seems to me a dangerous test, Alexander Parkhomov did, but I do not know how strong the ceramic reactor is).

      Andrea Rossi

      Steven N. Karels:

      As I said, until I do not know the particulars, I cannot comment this
      interesting experiment. The calorimetry used is the same that Prof.
      Focardi and I used in our initial experiments in 2008, or at least it
      seems so.

      Warm Regards,

      Dear Andrea Rossi,

      Some of the differences between the eCat reactor (The Lugano
      experiment) and the experiment performed by Prof. Parkhomov (the Russian
      experiment) are:

      a. the Lugano eCat had the dimensions of 200 mm in length, an outer
      diameter of 20mm and an estimated (by me) inner diameter of 12.7mm or
      1/2″ while the Russian experiment had a length of 120mm, an outer
      diameter of 10mm and an inner diameter of 5 mm. So the ratio of the
      eCat to the Russian interior volumes is different by a factor of 10.

      b. The Lugano eCat had 1 gram of fuel which I estimated to contain 0.55
      grams of nickel, up to .389 grams of iron, and 0.061 grams of LiAlH4.
      The Russian experiment had 1 gram of nickel and 0.1 grams of LiAlH4. So
      the Russian experiment had 1.64 times the amount of LiAlH4 than the
      Lugano experiment.

      c. The Lugano experiment used IR measurements of the surface
      temperature of the reactor while the Russian experiment used a phase
      transition of water (i.e., boiling) and loss of mass to estimate heat

      The Russian report estimated the interior pressure of the reactor at
      100 atm. Given the ratio of the volumes and the mass of the LiAlH4, one
      would estimate the interior pressure of the Lugano experiment at around
      6 – 10 atm – a valve previously reported to be in the correct range for
      eCat operation.

      My conclusion is that the Russian experiment lacked the “catalyst”
      that enables LENR+ reactions are lower pressures. So this is a partial
      replication of the Lugano experiment.

      • Bob Greenyer

        We will do Ni+ LiAlH4 as we always intended first, hopefully tomorrow

    • Axil Axil

      Regarding 10% < 3.150 microns. This means that
      Less than 10% of the powder is optimized for the operational temperature range of the test reactor.

    • Axil Axil

      The nano surface features of the Ni T255 powder look very good. There are lots of sharp peaks and valleys, and the size is right also. I predict excellent results using this powder.

      • Bob Greenyer

        If we assume it works, we agree this should be a good candidate for all the reasons you have identified.

        • LilyLover

          If ever this experiment fails, try applying industrial strength ultrasonic excitation. Usually I’m not the one advocating piezoelectric vibrations, but in this case, the nascent Hydrogen just might get a boost from this and some Van-Der-Walls magic on Ni lattice might be your resultant catalyst. I know it’s not the same as Rossi’s waves, but might be just the nudge that might suffice. Also even in the event of success, try this in the phase of “heat after death” of “dying down phase” of reaction.

        • Obvious

          Bob, once nickel powder is loaded with H, how long will it stay loaded in open air (in an envelope for example)?
          I’m wondering if the Ni powder needs to be pre-loaded.

  • Mike Ivanov

    I think the stampede is going to be in any case. The holy grail is free energy, not isotopic change. And main claim of Parkhomov test is huge and more or less stable COP. Btw, what happened with early Rossi’s claims about copper which appeared during the process and gamma-ray bursts? Was it a red herring or something like this?

    • Ged

      Likely it’s due to deuterium. Early test showed a lot more gamma radiation and copper production that seemed wholly linked to deuterium in the hydrogen gas. This is likely since the additional neutron would fundamentally change the reaction pathway.

      • Mike Ivanov

        These tests have been done only by Rossi. Lugano test did not show any radiation or traces of copper. Parkhomov test also did not show any gamma rays, so I suspect what Rossi a) tried to mislead other researchers in order to protect his IP b) used some other components in cold e-cat c) something else 🙂
        Bottom line: gamma rays or transmutation of nickel to copper never been reproduced yet.

  • Oceans2014

    Parkhomov method going viral? Dr Peter Gluck

  • Axil Axil

    Finding the optimum nickel particle size for the operation tempeture of Ni-H reactor.

    Load the operation Ni-H temperature in the line as follows:

    If the temperature is =1000C


    λpeak=x10^m = nm = microns.= 2.276243 microns.

    • Obvious

      Rather than tuning the particle size to a particular heat level, perhaps a continuous range of sizes tuned to a wider range will allow a larger window of effectiveness. Perhaps even a calibrated gap or two of ineffective particle size will allow a fail-safe temperature level to allow controlled shut-down or bracket the effective range to prevent run-away reactions.

  • Axil Axil

    Rossi once said that he no longer used a secret sauce for the hot Cat. This leads me to believe that Rossi does not understand the mechanism of how the secret sauce works. He used one(lithium) for the Hot Cat and did not know that it was a catalyst.

    Also, the number of resonant mechanisms that a reactor builder includes in their design means a greater COP that can be achieved.

    Many Ni-H reactors will be poor performers because these reactors do not include all the optimization mechanisms that they might have used.

  • If Parkhomov wants to achieve Rossi’s COP, he will have to use iron dust.

    So what about the big players? When will Mitsubishi, Toyota, Volvo, and NASA publicly admit that they have reproduced the “Rossi effect” using the same materials? NASA certainly by now has an idea of what “frequencies” to use for the electronic stimulation part. Even some of the posters to this forum seem to have a handle on that.

    • Gerard McEk

      It could be that iron has some function and possibly in combination with the high current pulses as a result from the applied triac controller, the high voltage and the low resistance of the heating wire.

      • I don’t know about that, but the iron dust helps break the H2 gas into H1. H2 gas does not do you any good in this reaction. If you want the most efficient design, you need allot of H1 to get into the nickel. More H1 equals more efficiency.

        • Obvious

          Maybe Rossi uses ground Ni-Fe meteorite.

  • I wonder how, for example NASA or big universities, would react if MFMP would send them an already assembled and working reactor and asking them to run, measure and replicate it.

    • Ivanidso

      How about MIT : )

      A chance for retribution!

    • Bernie777

      I am sure they already have one, what they are doing with it, and who is controlling the research and industrialization is what I would like to know.

    • Mike Ivanov

      I think not a chance. None of bureaucratic management in these places will approve financing for “Cold Fusion” in any visible amount. Why do you think Parkhomov run this test at home? Ask him.

  • Jarea

    I just wanted to say thanks to Alexander Parkhomov. Great scientists that has reached the hall of fame for his open scientific contribution reproducing the ecat.

  • bachcole

    Thank you, Professor Parkhomov, and, please, keep it up.

  • Bob Greenyer

    It is a good, established method, we use something similar for the Mizuno in France

  • James Andrew Rovnak

    Yes, thank you very much for the whole world! Truly another Patriot of mankind just as Andrea Rossi & others who work so earnestly & those who document these efforts for all to see!

  • LilyLover

    Best of luck for the Experiment. If ever this experiment fails – try applying industrial strength
    ultrasonic excitation of various frequencies. Also @ Resonance &120 degree phase off etc. Usually I’m not the one advocating piezoelectric
    vibrations, but in this case, the nascent Hydrogen just might get a
    boost from this and some Van-Der-Walls magic on Ni lattice might be your
    resultant catalyst. I know it’s not the same as Rossi’s waves, with his carefully crafted lattice, but
    might be just the nudge that might suffice. We are not aiming for 10X right now, so, 3X might suffice. Also even in the event of
    success, try this in the phase of “heat after death” or “dying down
    phase” of the reaction. (Corrected for errors.)

  • Bernie777

    Thank you Dr. Parkhomov for cooperating, the exchange of LENR research is important for the entire world.

  • Oceans2014

    Thank you Dr. Parkhomov > you came through huge !!
