Abstract

The mixed oxide of the invention mainly consists of cerium oxide and of at least one oxide of another rare earth. It has a specific surface area of at least 20 m/g after calcining at 1000° C. for 5 hours. It is obtained by forming a liquid medium comprising a cerium compound; by heating this medium; by adding to the precipitate obtained a compound of the other rare earth, by heating the medium thus obtained and by bringing its pH to a basic value and by calcining the precipitate. The mixed oxide may be used as a catalyst support.
