ABSTRACT:
A process for coating particulate zirconia for use in ceramics is claimed. The particulate zirconia is coated with a hydrous oxide of a stabilizing metal such as yttrium, an alkaline earth metal or a rare earth metal by hydrolysis of a salt of the metal. An initial dispersion of the zirconia is prepared at a pH above 7.5 and, preferably, in the presence of an organic dispersing agent.
The coated zirconia produced according to the process has been shown to form ceramic bodies with a higher strength than those prepared from particulate zirconia coated by prior known processes.
