A Synthesis and Characteristics for Zirconia Powders by Coprecipitation Method ; III) The Properties and Sinterabilities of ZrO2-Y2O3-Bi2O3

ABSTRACT

The physical properties and sinterabilities of ZrO2-Y2O3-Bi2O3 ternary system powder prepared by coprecipitation were investigated. The crystallization temperatures of ternary system were increased and the specific surface areas were decreased with increasing Bi2O3 amount as sintering agents both PSZ and FSZ. Especially, the partially stabilized zirconia showed monoclinic phase. The sinterability was increased with the amount of Bi2O3 added which caused liquid phase sintering.
