CERIUM OXIDE WITH MORPHOLOGICAL CHARACTERISTICS AND PROCESS FOR ITS PREPARATION

摘要

A ceric oxide with new morphological characteristics and one of the processes for obtaining the said oxide. The process of the invention is characterised in that a ceric hydroxide prepared by basic precipitation from a solution of a cerium salt is subjected to a solvothermal treatment before the calcination operation. The ceric oxide obtained has a large specific surface at high temperature.
