Abstract

The synthesis of polycrystalline H3O + -β/β″-Al2O3 ceramics is described. Design principals are detailed wherein the appropriate strength and conductivity are developed in a precursor K/Na- β/β″-Al2O3 ceramic based on microstructural refinement and mixed-alkali/percolation principals respectively. The resulting polycrystals are evaluated in steam electrolysis cells at 100° and 300°C.
