SINTERED ZIRCONIA, AND SINTERING COMPOSITION AND CALCINED OBJECT THEREFOR
Provided is sintered zirconia which can be inhibited from deteriorating at low temperatures. Also provided are a sintering composition and a calcined object which are precursors for the sintered zirconia. The burned surface of the sintered zirconia gives an X-ray diffraction pattern in which the ratio of the height of the peak present around the location where a [200] peak assigned to the cubic system is to appear to the height of the peak present around the location where a [200] peak assigned to the tetragonal system is to appear is 0.4 or more, and a region located at a depth of 100 µm or more from the burned surface gives an X-ray diffraction pattern in which the ratio of the height of the peak present around the location where a [200] peak assigned to the cubic system is to appear to the height of the peak present around the location where a [200] peak assigned to the tetragonal system is to appear is 0.3 or less.
