| titleOfInvention | Colored translucent zirconia sintered body and use thereof |
| abstract | 【Task】 An object of the present invention is a colored translucent zirconia that has a high density and strength of a sintered body and is excellent in color appearance and translucency close to the color tone of a tooth, in particular, a mill blank and an orthodontic bracket. The object is to provide a sintered body. [Solution] 2～4Mol% yttria, the 0.02～0.8Mol% of Er 2 O 3, Fe 2 O 3 of iron compound and less than 0.005～0.2Wt% less than 20~2000ppm in terms Al 2 O 3 A zirconia sintered body containing the remainder being zirconia, the lightness L * of the color parameters specified in JIS-Z8729 is 55 to 75, a * is 0 to 10, b * is 0 to 30, A colored translucent zirconia sintered body having a density of 99.80% or more and a total light transmittance of 18% to 40% by a D65 light source at a sample thickness of 1 mm. Wherein 2～4Mol% yttria, cobalt oxide of less than 0.01 wt% in terms of CoO, iron oxide less than 20~2000ppm in terms of Fe 2 O 3, the Al 2 O 3 less than 0.005～0.2Wt%, The balance is a zirconia sintered body having zirconia as the balance, the lightness L * of color parameters specified in JIS-Z8729 is 50 to 75, a * is -1 to 10, b * is 0 to 30, and the relative density 99.80% or more, and the total light transmittance with a D65 light source at a sample thickness of 1 mm is 18% or more and 40% or less. [Selection figure] None |
