GRAYED OXIDE CERAMIC SINTERED COMPACT, AND PRODUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide an oxide ceramic sintered compact which has a low thermal expansion rate and a high Young's modulus, hardly transmits/scatters a lase beam or the like to be used for positioning, and has a desired gray color tone.SOLUTION: The oxide ceramic sintered compact includes three phases of cordierite, mullite and sapphyrin as a crystalline phase, contains MgO, AlOand SiOas a matrix composition comprising the crystalline phase, has a cordierite phase as a main component, contains oxides of two or more elements selected from the group consisting of Fe, Cr, Co, Cu and Mn by 0.3-1.0 mass% as a colorant component other than the matrix component, and has the L*(L star) value of 40-65, which value is stipulated by JIS Z8729 as brightness, the average thermal expansion rate of -0.2×10/°C to 0.2×10/°C at 21°C to 23°C and the Young's modulus equal to or higher than 140 GPa.
【課題】低熱膨張率と高ヤング率を有し、位置決めに使用されるレーザー光等の透過、散乱を起させない所望の灰色の色調を有する酸化物セラミックス焼結体の提供。【解決手段】結晶相としてコーディエライト、ムライト及びサフィリンの３相を含む酸化物セラミックス焼結体であって、結晶相を構成する母組成として、ＭｇＯ、Ａｌ2Ｏ3及びＳｉＯ2を含有し、コーディエライト相を主成分とし、前記母組成以外に、着色剤成分として、Ｆｅ、Ｃｒ、Ｃｏ、Ｃｕ、および、Ｍｎからなる群から選択される二種以上の元素の酸化物を０．３〜１．０質量％含有し、明度がＪＩＳ Ｚ８７２９に規定されるＬ＊（エルスター）の値で４０〜６５であり、２１℃〜２３℃における平均熱膨張率が−０．２?１０-6〜０．２?１０-6/℃であり、かつ、ヤング率が１４０ＧＰａ以上である酸化物セラミックス焼結体。【選択図】図１
