<P>PROBLEM TO BE SOLVED: To provide a zirconia sintered compact having high fracture toughness, a sintering composition to become a precursor of the zirconia sintered compact and a calcined object. <P>SOLUTION: The zirconia sintered compact has partially stabilized zirconia containing a stabilizer as a matrix phase, wherein the standard deviation of the surface concentration of the stabilizer is ≥0.8 when the concentration of the stabilizer in each square formed by dividing 10 μm×10 μm area into 256 squares×256 squares lattice in the sample surface of the zirconia sintered compact is expressed by mass%. <P>COPYRIGHT: (C)2011,JPO&INPIT |
