Two aluminum oxyhydroxides, boehmite and pseudoboehmite, and two aluminium hydroxides, bayerite and gibbsite, have been investigated as precursors for the synthesis of the solid electrolyte, beta alumina. Reaction pathways and products have been characterized by thermal analysis and powder X-ray diffraction. A solid state reaction model for the formation of [beta][double prime]-Al[sub 2]O[sub 3] is proposed.
