摘要： PROBLEM TO BE SOLVED: To solve such the problem that although light-permeable zirconia sintered bodies can be improved in light permeability by incorporating titania thereinto, the mechanical strength of the sintered bodies is deteriorated.
SOLUTION: A titanium oxide-containing zirconia sintered body containing 6 to 15 mol% of yttria and 3 to 20 mol% of titania and having an average bending strength of 250 MPa or more and linear permeability of 50% or more as measured using a 1 mm-thick sample at a measurement wavelength of 600 nm is provided. In a production process comprising, for example, shaping a zirconia powder containing 6 to 15 mol% of yttria and 3 to 20 mol% of titania, and carrying out hot isostatic press (HIP) processing of the primary sintered body obtained by normal primary sintering of the shaped product, the sintered body is produced so as to have an average grain diameter less than 30 μm.
