ZIRCONIA CALCINED BODY
To provide at least any of a layered body which has a change in color tone and in which it is unnecessary to select a colorant and the content of the colorant in consideration of a difference in the sintering behavior between layers, a precursor thereof, and a method for producing them.SOLUTION: A calcined body is provided that has structure in which two or more layers containing stabilizer-containing zirconia and a colorant are layered, and in which types and contents of the colorants contained in the layers are equal to each other, the layered body including at least: a first layer containing a colorant and zirconia which has a stabilizer content of higher than or equal to 3.3 mol%; and a second layer containing a colorant and zirconia which has a stabilizer content different from that of the zirconia contained in the first layer.SELECTED DRAWING: None
【課題】層毎の焼結挙動の相違を考慮した着色剤及びその含有量の選定を要せず、色調の変化を有する積層体、その前駆体、又はそれらの製造方法の少なくともいずれかを提供する。【解決手段】安定化剤を含有し、なおかつ、ネッキング構造を有するジルコニアと、着色剤とを含むジルコニア組成物層が２層以上積層した構造を有し、なおかつ、各ジルコニア組成物層に含まれる着色剤及びその含有量が互いに等しく、少なくとも、安定化剤の含有量が３．３ｍｏｌ％以上であるジルコニアと、着色剤とを含む第１のジルコニア組成物層と、前記第１のジルコニア組成物層に含まれるジルコニアと安定化剤の含有量が異なるジルコニアと、着色剤とを含む、第２のジルコニア組成物層と、を備えることを特徴とする仮焼体、を提供する。【選択図】 なし
