Abstract
A method for producing .gamma.-form lithium aluminate powders usable as a material for an electrolyte tile of molten carbonate fuel cells which comprises mixing aluminum alkoxide with one member selected from the group consisting of the lithium salts of inorganic and organic acids, lithium hydroxide and lithium oxide in the presence of a non-aqueous solvent, carrying out reaction with addition of water of 1.5 to 20 moles (including water of crystallization contained in the lithium compound) based on 1 mole of aluminum alkoxide with stirring, and removing the solvent to obtain a solid matter which is then calcined at a temperature in a range of from 650.degree. C. to 1000.degree. C.
