POWDER COMPOSITION, CALCINED BODY, SINTERED BODY, AND METHOD FOR PRODUCING SAME
Provided is a powder composition that includes, as a matrix, a zirconia having a high content of a stabilizing element and that can provide, through short-time sintering, a sintered body satisfying translucency and mechanical strength required for dental prosthetic materials, in particular, prosthetic anterior teeth. Provided is a powder composition including two or more stabilized zirconias having different contents of a stabilizing element, in which the powder composition has a content of the stabilizing element of more than 4.0 mol % and 5.8 mol % or less, a rate of change in thermal shrinkage rate per unit temperature at 1,300° C. is 0.07% C−1 or less, and the contents of the stabilizing element of the stabilized zirconias are each 8.0 mol % or less.
