Date Nov. 12, 1992.The invention relates to methods for producing stabilized zirconium oxide powder suitable for pressing shaped elements and subsequent sintering to provide high-density ceramic materials. To this end, an aqueous solution of a zirconium salt containing an additive is converted into droplets. The droplets formed are solidified, by the action of ammonia, into gel particles which are then washed, dewatered dried and calcined. |
