ABSTRACT:
Ceric oxide particulates having a specific surface of at least 190 m.sup.2 /g, measured after calcination at a temperature of from 350.degree. to 450.degree. C., and a specific surface of at least 15 m.sup.2 /g after calcination at 800.degree. C., are prepared by (a) suspending, in an aqueous solution of a decomposable base, a ceric hydroxide of the formula (I):
