ABSTRACT:
Novel rare earth oxides having a large specific surface of at least 40 m.sup.2 /g, well adapted for catalysis, are prepared (i) by reacting at least one rare earth salt with a strong base in the presence of carboxylate ions, or by reacting at least one rare earth carboxylate with a strong base, to produce a true rare earth hydroxide, (ii) separating the precipitate thus produced, and then (iii) washing and (iv) calcining such precipitate.
