ABSTRACT:
Zirconia has been used in the manufacture of ceramics for many years. The desirability of stabilizing the crystal form has been recognized and one or more stabilising agents have been used. The present invention produced a stabilized zirconia carrying a coating of at least one hydrous oxide of yttrium, calcium, magnesium, strontium, barium, or cerium. Preferably also a hydrous oxide of zirconium is also present either a s a separate inner layer or mixed with the other hydrous oxide.
