Al4SiC4 COMPOSITION OR Al4SiC4 POWDER, AND METHOD OF PRODUCING THE SAME
To provide an Al4SiC4 composition or Al4SiC4 powder not substantially including Al4C3 and not substantially including sulfur.SOLUTION: In the Al4SiC4 composition or Al4SiC4 powder, the ratio of the integrated intensity IAl4C3/IAl4SiC4, namely the ratio of the integrated intensity, IAl4C3 (cps deg) of the diffraction peak of Al4C3 in the vicinity of 2θ=55.1° relative to the integrated intensity IAl4SiC4 (cps deg) of the diffraction peak of Al4SiC4 in the vicinity of 2θ=56.0° measured by powder X-ray diffraction is 0.1% or lower and the sulfur content is 150 mass.ppm or less.SELECTED DRAWING: Figure 1
【課題】Ａｌ４Ｃ３を実質的に含まず、かつ硫黄を実質的に含まないＡｌ４ＳｉＣ４組成物又はＡｌ４ＳｉＣ４粉末を提供する。【解決手段】粉末Ｘ線回折で測定された２θ＝５５．１°付近におけるＡｌ４Ｃ３の回折ピークの積分強度ＩＡｌ４Ｃ３（cps・deg）と２θ＝５６．０°付近におけるＡｌ４ＳｉＣ４の回折ピークの積分強度ＩＡｌ４ＳｉＣ４（cps・deg）との比率ＩＡｌ４Ｃ３／ＩＡｌ４ＳｉＣ４が０．１％以下であり、かつ、硫黄含有量が１５０mass ppm以下であるＡｌ４ＳｉＣ４組成物又はＡｌ４ＳｉＣ４粉末である。【選択図】図１
