ZIRCONIA COMPOSITION, ZIRCONIA CALCINED BODY, ZIRCONIA SINTERED BODY, METHOD FOR PRODUCING ZIRCONIA CALCINED BODY, AND METHOD FOR PRODUCING ZIRCONIA SINTERED BODY
The present invention provides a zirconia composition that exhibits excellent translucency in its sintered body and that enables the mitigation of opalescent properties in the sintered body. The invention also provides a zirconia pre-sintered body and zirconia sintered body therefrom, along with methods that enable easy production of these. The present invention relates to a zirconia composition comprising a zirconia particle, and a stabilizer particle capable of preventing a phase transformation of zirconia, wherein: the zirconia has an average particle diameter (r1) of 1 to 60 nm, the stabilizer has an average particle diameter (r2) of 1 to 60 nm, and the half width of a peak derived from the stabilizer in a powder X-ray diffraction pattern by CuKα radiation is 0.05° to 1.0°. Using the zirconia composition allows the zirconia sintered body to exhibit reduced regularity in its structure, mitigating wavelength-selective reflection and/or transmission, resulting in reduced opalescent properties. This leads to the production of a zirconia sintered body that exhibits excellent translucency and low opalescent properties.
