TRANSLUCENT ZIRCONIA SINTERED BODY, METHOD FOR MANUFACTURING SAME, AND USE THEREOF
Provided is a zirconia sintered body having both high translucency and high strength. The zirconia sintered body includes crystal grains that include a cubic domain and a tetragonal domain, wherein a stabilizer and lanthanum is dissolved as a solid solution therein. The sintered body can be obtained by a manufacturing method including: a mixing step of obtaining a mixed powder by mixing a zirconia source, a stabilizer source, and a lanthanum source; a molding step of obtaining a green body by molding the obtained mixed powder; a sintering step of obtaining a sintered body by sintering the obtained green body at a sintering temperature of 1650°C or higher; and a temperature lowering step of lowering the temperature from the sintering temperature to 1000°C at a temperature lowering rate exceeding 1°C/min.
