ZIRCONIA SINTERED COMPACT HAVING HIGH LINEAR LIGHT TRANSMITTANCE
The present invention provides a zirconia sintered body that excels in both translucency and strength and excels in linear light transmittance with no use of an HIP device, and a zirconia molded body and a zirconia pre-sintered body from which such a zirconia sintered body can be obtained. The present invention relates to a zirconia molded body comprising zirconia particles comprising 2.0 to 9.0 mol% yttria, having an average primary particle diameter of 60 nm or less, and including 0.5 mass% or less zirconia particles having a particle diameter of more than 100 nm, wherein the zirconia molded body has ΔL*(W - B) of 5 or more through a thickness of 1.5 mm. The present invention also relates to a zirconia pre-sintered body comprising 2.0 to 9.0 mol% yttria, wherein the zirconia pre-sintered body has ΔL*(W - B) of 5 or more through a thickness of 1.5 mm. The present invention further relates to a zirconia sintered body comprising: a fluorescent agent; and 2.0 to 9.0 mol% yttria, wherein the zirconia sintered body has a linear light transmittance of 1% or more through a thickness of 1.0 mm.
