iAlumina and Y203－partially stabilized zirconia（PSZ） which were typical oxide ceramics were heat－treated in vacuum in holding time of 3h and the temperatures between 1300℃ and 1600℃． All test pieces showed mass loss by the heat－treatment．The amount of mass loss of the alumina was more abounding than that of the Y203－PSZ．Though the mass loss seemed to be due to vaporization from the sample surface，vapor species did not be identified．Bending strength of alumina and Y203－PSZ did not show the remarkable change by heat treatment up to 1500℃，but decreased suddenly at 1600℃．It is considered that one of the factors of strength degradation is the grain growth by heat-treatment．In case of the alumina，Vickers hardness showed the decrease of about 10％ up to1500℃ and the decrease of about 30％ at l600℃． In case of the Y203－PSZ，Vickers hardness showed the decrease of about 10％i n all tested temperature range．The degree of degradation of measured physical property of the Y203 PSZ was smaller than that of the alumina． The Y203－PSZ was more stable than the alumina for heat treatment．
