Abstract
A process for making a fully or a partially stabilized zirconia is disclosed. The process comprises making an aqueous solution of zirconium sulfate in admixture with an inorganic or organic water soluble salt of one or more metals selected from the group consisting of Be, Mg, Ca, Sr, Ba, Ra, Sc, Y, La, Ac, Ce, Hf, Th and Al. The aqueous solution is atomized into a solvent at least partially miscible with water with the solvent being agitated during the addition of the solution. The coprecipitated metal salt formed is separated from the solvent, washed with inert solvent or solvents, dried, and calcined.
