Abstract

In the production of sintered zirconium dioxide by heating to temperatures above 2000 DEG F, from 0,5 to 2% by weight of magnesium, cerium or aluminium oxides, or compounds giving rise thereto, are added as a sintering catalyst. According to an example, a zirconium dioxide of particle size from 1 to 4 microns was mixed with 0,5 to 1,5 of magnesia, 1 to 1,5% by weight of cerium or 1% by weight of alumina, moulded and sintered at 2150 DEG C. An apparent density of between 5,3 and 5,5 was attained.
