Abstract
Preparations and uses are shown for novel crystalline aluminates which conform generally to the empirical formula EQU MgA.sub.a.sup.v Z.sub.b.sup.v.nAl(OH).sub.3.mH.sub.2 O PA1 where A and Z represent negative-valence ions or radicals selected from the group comprising hydroxyl, halide, inorganic acid, and organic acid, PA1 n is a value of from about 1 to about 2, PA1 v is a negative valence of 1, 2, or 3, PA1 a and b each have values of from zero to 2, PA1 with (va)+(vb) equal to 2, and PA1 with m being a value of zero or more.
