LIGHT-TRANSMISSIVE ZIRCONIA SINTERED BODY AND PREPARATION METHOD THEREFOR AND USE THEREOF
Provided is a light-transmissive zirconia sintered body, obtained by preparing a green body from a powder for the light-transmissive zirconia sintered body by means of isostatic pressing, and sintering the green body at a high temperature and normal pressure after degreasing and biscuit firing. The light-transmissive zirconia sintered body is prepared by dispersing zirconia powder in water, adding an appropriate amount of a dispersant and a binder, mixing the mixture to form a slurry, and spray-granulating same, wherein the molar percentage of yttrium oxide in the zirconia powder is 3-5%. The light-transmissive zirconia sintered body can be used for preparing a fixed dental prosthesis.
