Lithium Corrosion (Axil Axil)

The following post has been submitted by Axil Axil

High temperature lithium corrosion seems to be presenting a major problem in material engineering of the LENR ceramic tube reactor. Using a metal tube is problematical because lithium dissolves metals through a voracious alloying process and ceramics are short lived because lithium readily combines with oxygen, nitrogen, and carbon until a saturation point is reached. When a lot of lithium is needed that saturation point might not occur until after the ceramic tube has failed.

I would bet that Rossi is trying to find a lithium resistant material for the tube of his new the E-Cat-X reactor. Very high operating temperatures that the E-Cat X is running at makes lithium vapor corrosion intense.

One solution to this very difficult high temperature corrosion problem might be to uses a ceramic that contains lithium that has already reached the saturation level. “LITHIUM DISILICATE GLASS” might be resistant to lithium corrosion. A test of this material that is an alternative ceramic material used in dental crowns might be worth testing for high temperature lithium corrosion resistance.

http://sgiglass.com/ is a supplyer and fabrocator of this material. Such a fabricator might be tasked to produce a tube made from this material.

This solution might be out of the price range of the typical replicator.

Another idea is to use this glass as a surface coating just a few nanometers thick on both the inside and outside of a refractory metal tube using vapor disposition. Because we would be using a minimum of bulk material this method would not cost too much to do if the replicator can do it himself. The expansion of the coating would need to match the expansion coefficient of the refractory metal that is being used(tungsten?).

    Axil, LITHIUM DISILICATE GLASS is sounding very close to me to DILITHIUM CRYSTALS! That is the LENR material we have been searching for.
    Just kidding Axil, I always appreciate your thoughtful posts and suggestions and will look into this as a possible material to incorporate in my reactors.

    New research shows candle soot can power the lithium batteries in electric cars

    The soot from candles will repel just about any liquid. It will be used in lithium car batteries to protect the anode from lithium corrosion.

    It might be worth an experiment fo see if candle soot can protect and preserve lithium from combining with the materials used inside the LENR reactor.

    You said:

    “What if Lithium, as a penetrating corrosive agent (especially in the case of Nickel), is accelerating the embrittlement/corrosion process so that eventually, yet at a quicker rate than normal, the right nanoscale structures can appear on the metal?”

    This is a good observation. This fits in with the fuel preprocessing that Rossi has done as seen in the Lugano test. The 100 micron nickel particle that the preprocess method produces is covered with lithium throughout its entire surface area. During preprocessing, the application of lithium at high temperatures might erode the surface of the nickel particle(S) to form nanocavities as happens in palladium at high hydrogen loading levels. Maybe the crack idea of Ed Storms holds merit.

    Parkhomov uses a low quality powder with lots of carbon on the surface. Lithium processing might erode that carbon and leave nano cavities on the surface of the nickel powder as occurs in palladium at high hydrogen loading. Maybe the Russian nickel powder is good because it is so poor in production. A powder with abundant carbon content might be the best type of powder to use.

    Furthermore, the surface of the nickel powder becomes saturated with lithium to the point where lithium is no longer consumed in nickel alloying. When the reaction begins with LAH, lithium is no longer consumed and remains free and available for the LENR reaction to use.

    Another thing that could be happening in the high carbon surface preprocessing of Russian nickel powder is that lithium carbide is formed on the surface of the powder. These lithium compound might produce both lithium and hydrogen Rydberg matter during the reaction stage through a desorption process.
