Evaluating a new material for Hall-Héroult cell cathodes

Ti3SiC2 showed a significant degree of corrosion resistance in contact with molten cryolite. Corrosion resistance was observed despite the oxidizing conditions employed and the significant portion of TiC contamination observed in hot-pressedparts.

This favorable outcome supports proposed follow-up activities, including more extensive corrosion testing, more thorough characterization of the corroded material, and confirmation of the reported physical and electrical performance for the material. Following the successful conclusion of these tests, an evaluation of the material in a benchscale electrochemical cell can be performed.
