Abstract
To provide at least one of a sintered body with both high dynamic strength and high static strength, a method for producing the sintered body, a powder and a calcined body. A sintered body of zirconia, wherein the zirconia contains a stabilizing element, the stabilizing element contains at least one rare-earth element other than yttrium, and the sintered body has an average grain size of 0.05 μm or more and 0.75 μm or less and has a plastic deformable region.

A sintered body of zirconia, wherein the zirconia contains a stabilizing element, the stabilizing element contains at least one rare-earth element other than yttrium, and the sintered body has an average grain size of 0.05 μm or more and 0.75 μm or less and has a plastic deformable region.
A zirconia powder comprising zirconia containing a stabilizing element and having a monoclinic fraction of more than 70%, wherein the stabilizing element includes at least one rare-earth element other than yttrium.
A calcined body comprising zirconia containing a stabilizing element and having a monoclinic fraction of more than 70%, wherein the stabilizing element includes at least one rare-earth element other than yttrium.
