Zirconia composition, zirconia pre-sintered body, zirconia sintered body, and dental product
Provided are a zirconium oxide composition, a zirconium oxide presintered body, a zirconium oxide sintered body, and a dental product in which the occurrence of defects is suppressed and the transparency is changed. The zirconia sintered body contains 4 mol%-7 mol% of yttrium oxide as a stabilizer. The zirconia sintered body contains a light-blocking material. The zirconia sintered body has a first region and a second region having a higher light-blocking material content than the first region. The difference between the content of yttrium oxide in the first region and the content of yttrium oxide in the second region is 1 mol% or less.
提供抑制缺陷的发生且透明性会变化的氧化锆组合物、氧化锆预烧体和氧化锆烧结体、以及齿科用制品。氧化锆烧结体中含有4mol％～7mol％的氧化钇作为稳定剂。氧化锆烧结体含有遮光材料。氧化锆烧结体具有第一区域、以及遮光材料的含有率比第一区域高的第二区域。第一区域中的氧化钇的含有率与第二区域中的氧化钇的含有率之差为1mol％以下。
