MULLITE-BASED SINTERED COMPACT AND METHOD FOR PRODUCING THE SAME
To provide a mullite-based sintered compact having a small content of other components than aluminum oxide and silicon oxide that are mullite constituent components, and excellent in thermal shock resistance and mechanical strength, and to provide a method for producing such a mullite-based sintered compact.SOLUTION: Disclosed is a mullite-based sintered compact containing an yttrium element in an yttrium oxide-equivalent amount of 0.01 to 0.25 mass%, wherein: the average particle size of the mullite crystal particles 1 that constitute the sintered compact is 1.00 to 3.00 μm; and the average aspect ratio of the mullite crystal particles 1 is 1.65 or less.SELECTED DRAWING: Figure 1
【課題】ムライト組成成分である酸化アルミニウム及び酸化ケイ素以外の成分の含有量が少なく、耐熱衝撃性及び機械的強度に優れたムライト質焼結体及びその製造方法を提供する。【解決手段】イットリウム元素を酸化イットリウム換算で０．０１〜０．２５質量％含むムライト質焼結体であって、前記焼結体を構成するムライト結晶粒１の平均粒径が１．００〜３．００μｍであり、前記ムライト結晶粒１の平均アスペクト比が１．６５以下である、ムライト質焼結体。【選択図】図１
