Screening tests were conducted on 25 ceramics to evaluate their suitability as insulators in a Downs‐type lithium electroreduction cell. Each material was exposed to molten lithium at 400°C for 100 h. Of the materials tested, beryllia, magnesia, yttria, yttrium aluminum garnet, and aluminum nitride were found to have acceptable compatibility with lithium. It is reasonable to expect that they are also compatible with molten electrolyte. These candidate materials can therefore be selected for various cell components based on fabricability or other considerations.
