Abstract
The purpose of the present invention is to provide an industrially advantageous method for producing α-lithium aluminate which has physical properties that are suitable for use as an electrolyte holding plate of a MCFC having excellent thermal stability, even if the α-lithium aluminate is a fine material having a BET specific surface area of 10 m/g or higher in particular. Provided is a method for producing α-lithium aluminate characterized by subjecting a mixture (a), which is obtained by mixing transitional alumina and lithium carbonate at an Al/Li molar ratio of 0.95-1.01, to a first firing reaction so as to obtain a fired product, and subjecting a mixture (b), which is obtained by adding an aluminum compound to the obtained fired product at quantities whereby the molar ratio of aluminum atoms in the aluminum compound relative to lithium atoms in the fired product (Al/Li) is 0.001-0.05, to a second firing reaction.
