ZIRCONIA CUT BODY FOR DENTAL CUTTING CONTAINING In AND Y
To provide a technique for giving a zirconia sintered body high light-transmissivity comparable to that of natural tooth enamel.SOLUTION: A zirconia cut body for dental cutting contains, as stabilizers, a yttrium compound and an indium compound, with the content of the yttrium compound being 3.0 mol%-6.0 mol% in terms of oxides and the content of the indium compound being 0.2 mol%-3.0 mol% in terms of oxides, and the total of the yttrium and indium compounds being 5.5 mol%-7.0 mol% in terms of oxides.SELECTED DRAWING: None
【課題】ジルコニア焼結体に天然歯エナメル質同様の高い透光性を付与する技術が求められていた。【解決手段】歯科切削加工用ジルコニア被切削体であって、安定化剤としてイットリウム化合物及びインジウム化合物を含み、イットリウム化合物を酸化物換算で３．０ｍоｌ％～６．０ｍоｌ％で含み、インジウム化合物を酸化物換算で０．２ｍоｌ％～３．０ｍоｌ％で含み、イットリウム化合物とインジウム化合物の合計が酸化物換算で５．５ｍоｌ％～７．０ｍоｌ％であることを特徴とする歯科切削加工用ジルコニア被切削体とする。【選択図】なし
