Zirconium oxide sintered body, zirconium oxide powder, and method for producing zirconium oxide sintered body
A zirconia sintered body including stabilized zirconia including zirconia and a stabilizer, the stabilizer including an oxide of yttrium and an oxide of M, M being one or more elements selected from the group consisting of Ca, Ba, Sr, Dy, Tb, Gd, Eu, Sm, Nd, Pr, and La, the content of the stabilizer in the stabilized zirconia being 1.7-2.6 mol% in terms of oxide, and the content of the stabilizer in the stabilized zirconia being 1.7-2.6 mol% in terms of oxide. The mol ratio of the oxide of M to the oxide of yttrium [(oxide of M)/(oxide of yttrium)] is 0.05-1.5, and the crystal grain diameter is 0.20 [mu] m or less.
