Useful compositions are prepared by incorporating into organic materials, crystalline lithium aluminates which conform substantially to the empirical formula n n (LiA.sub.x).sub.y.2Al(OH).sub.3.nH.sub.2 O n n where A represents one or more anions and/or negative-valence radicals, n where x represents a quantity of A ions and/or radicals sufficient to substantially satisfy the valence requirements of the Li, n where y is a numerical value sufficient to maintain the crystalline structure, n and where n represents the number of waters of hydration, if any. |
