摘要
There are provided zirconia composition, zirconia semi-sintered body and zirconia sintered body, and dental product in which defect-generation is suppressed and transparency varies. The zirconia sintered body contains 4 mol% to 7 mol% of yttria as stabilizer. The zirconia sintered body contains shielding material. The zirconia sintered body comprises first region and second region having a higher content ratio of the shielding material than the first region. Difference between content ratio of yttria in the first region and that of yttria in the second region is 1 mol% or less.
