摘要: A zirconia sintered body is provided having a color tone equivalent to the guides of various natural teeth and same aesthetics as front tooth. The present invention provides colored translucent comprising containing greater than 4.0 mol % not 6.5 yttria, less 0.25 erbia, 2,000 ppm iron oxide in terms Fe 2 O 3 , 0.01 wt. cobalt CoO, 0.1 alumina; relative density 99.90%, total light transmittance 25% 40% for wavelength 600 nm at sample thickness 1.0 mm, strength 500 MPa.
