PINK-COLORED ZIRCONIA SINTERED BODY AND METHOD FOR PRODUCING THE SAME
To provide a zirconia sintered body, which is a zirconia sintered body containing an erbia (ErO), and that can visually be recognized as a sintered body exhibiting a pinkish color tone, especially a warm pink color, even if the thickness is made to be 1 mm or less.SOLUTION: A zirconia sintered body, characterized by containing an aluminum by 3.0 mass% or more and 30.0 mass% or less in terms of AlOconversion, an iron by 0.01 mass% or more and 2.0 mass% or less in terms of FeOconversion, and a cobalt by less than 0.1 mass% in terms of CoOconversion, the balance being a zirconia containing an erbia by 2 mol% or more and 4 mol% or less, and containing aluminum oxide particles and yet the total light transmittance for a D65 light source at a sample thickness of 1.0 mm is 5% or less.SELECTED DRAWING: None
【課題】エルビア（Ｅｒ２Ｏ３）を含むジルコニア焼結体であって、厚みを１ｍｍ以下にとしてもピンク系統の色調、特に温かみのあるピンク色、を呈する焼結体として視認されうるジルコニア焼結体を提供する。【解決手段】Ａｌ２Ｏ３換算で３．０質量％以上３０．０質量％以下のアルミニウム、Ｆｅ２Ｏ３換算で０．０１質量％以上２．０質量％以下の鉄、及び、Ｃｏ３Ｏ４換算で０．１質量％未満のコバルトを含有し、残部が２ｍｏｌ％以上４ｍｏｌ％以下のエルビアを含有するジルコニアであり、アルミニウム酸化物の粒子を含み、なおかつ、試料厚み１．０ｍｍにおけるＤ６５光源に対する全光線透過率が５％以下であることを特徴とするジルコニア焼結体。【選択図】なし
