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?).
