The research program was designed to investigate candidate materials under conditions where material properties, performance, and failure modes can be interpreted with a level of confidence that is not possible with the poorly defined polycrystalline materials used in previous research. Two classes of candidate materials have been investigated. One is single-crystal materials grown in the uniquely controlled conditions achievable with the MIT laser-heated floating-zone crystal growth apparatus. The second comprises high purity powder synthesized from laser-heated gases. Produced samples were characterized in terms of fundamental material properties as well as those technological parameters which reflect exposures typical of the Hall cell. Objective is to define material compositions, critical fabrication process steps, and critical operating conditions which must be known before economically viable inert anodes and cathodes that exhibit adequate performance characteristics can be made.
