Influence of the Synthesis Conditions on the Properties of Powders and Ceramics Based on Zirconium Dioxide Partially Stabilized by Yttrium Oxide

Abstract

Xerogel in the ZrO₂–Y₂O₃ system s are obtained by using the traditional method of coprecipitation of hydroxides and in a microreactor with countercurrent intensely swirling flows of reagents. Their physical and chemical properties are studied. The patterns of influence of the synthesis method on the phase composition of powders and ceramics based on zirconium dioxide are revealed. Ceramic materials with high strength characteristics, consisting of a mixture of cubic and tetragonal modifications of ZrO₂ are obtained.
