A METHOD FOR PRODUCING LITHIUM ALUMINATE POWDERS

摘要

gamma -form lithium aluminate powder, useful for electrolyte tiles of molten carbonate fuel cells is obtained by mixing aluminum alkoxide with a lithium salt of an inorganic or organic acid, lithium hydroxide or lithium oxide in the presence of a non-aqueous solvent, and 1.5 to 20 moles water (including any water of crystallization contained in the lithium compound) per mole of aluminum alkoxide, and removing the solvent to give a solid which is calcined at 650 DEG C to 1000 DEG C.
