ABSTRACT:
Stabilised zirconia is obtained by mixing zirconia with an impure yttria concentrate containing 35-70% by weight yttria with the remainder being substantially heavy and light rare earth metal oxides, such concentrate being prepared from a naturally occurring mineral material. Sufficient concentrate is used so that the stabilised zirconia body contains at least 3 mole percent of yttria and heavy rare earth metal oxides.
