Abstract
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 m.sup.2 /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 m.sup.2 /g and a lithium compound, and then baking and reacting said compound in solid-phase.
