alpha-Lithium aluminate and method of manufacturing the same, and electrolyte support material of molten carbonate fuel cell

摘要

An alpha-lithium aluminate obtained through a solid-phase reaction of a gamma-alumina and a lithium compound, wherein said alpha-lithium aluminate comprises particles having a round shape, with a BET specific surface area in the range of 4-7 m2/g, and substantially not including gamma-lithium aluminate. Further, said alpha-lithium aluminate is manufactured by dry-mixing a gamma-alumina having a BET specific surface area in the range of 70-140 m2/g and a lithium compound, and then baking and reacting said compound in solid-phase.
