ABSTRACT:
Morphologically improved cerium oxide particulates having low sulfur content, useful, e.g., as catalysts/catalyst supports, and having a B.E.T. specific surface of at least 85.+-.5 m.sup.2 /g, measured at a temperature ranging from 350.degree. C. to 500.degree. C., are prepared by reacting an aqueous solution of cerium (IV) salt with an aqueous solution of sulfate ions to precipitate a basic ceric sulfate, filtering the precipitate which results, washing and optionally drying said precipitate, and then calcining same.
