Abstract
Useful compositions are prepared by incorporating into organic materials, crystalline lithium aluminates which conform substantially to the empirical formula (LiA.sub.x).sub.y.2Al(OH).sub.3.nH.sub.2 O where A represents one or more anions and/or negative-valence radicals, where x represents a quantity of A ions and/or radicals sufficient to substantially satisfy the valence requirements of the Li, where y is a numerical value sufficient to maintain the crystalline structure, and where n represents the number of waters of hydration, if any.
Claims6
Crystalline lithium aluminate compounds conforming essentially to the formula
- (Li+A.sup.-v.sub.l/v).sub.y.2Al(OH).sub.3.nH.sub.2 O
- wherein A represents a multivalent radical of a polycarboxylic compound, said A conforming to the formula
- R(COO.sup.-).sub.x
- where x is a numerical value of at least 4, and where R is an organic moiety to which the carboxylic groups are attached,
- where v is a valence of at least 4,
- where l/v is a quantity of A ions or radicals sufficient to substantially satisfy the valence requirements of Li,
