Abstract
Crystalline LiOH.2Al(OH.sub.3.nH.sub.2 O is reacted in aqueous solution with anions (A) having a valence of 1, 2, or 3 to form novel lithium aluminates conforming substantially to the empirical formula EQU (LiA.sub.x).sub.y.2Al(OH).sub.3.nH.sub.2 O where n is the number of waters of hydration, y is the number of lithium atoms present for each 2Al atoms, A has a negative valence of 1, 2, or 3, and x is the reciprocal of the valence of A.
