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