ABSTRACT:
Morphologically improved ceric oxide particulates having a grain size distribution such that the mean diameter of the aggregates thereof ranges from 0.2 to 1 .mu.m, are conveniently prepared by (i) hydrolyzing an aqueous solution of a cerium (IV) salt in an acid medium, in the presence of an aqueous colloidal dispersion of a cerium (IV) compound, (ii) separating the resulting precipitate, and (iii) heat treating said separated precipitate, advantageously by calcination at elevated temperatures.
