PREPARATION OF HIGH PURITY, HOMOGENEOUS ZIRCONIA MIXTURES ABSTRACT OF THE DISCLOSURE A method is provided of preparing high-purity mixtures of zirconia and another metal oxide substantially free of sodium oxide impurity. An acidic solution of carbonated hydrous zirconia and a salt of another metal is added to a highly basic solution, resulting in the homogeneous precipitation of the combined hydroxides or hydrous oxides. The precipitate is recovered, washed with water and then with an organic solvent, and then dried, most preferably employing an azeotropic distillation procedure. The resulting material is then calcined to provide a mixture of zirconia with the other metal oxide. In a preferred embodiment, the zirconia mixtures are in the form of fine powders which can be sintered to form a product having greater than 99% of its theoretical density
