用光学显微镜、图像分析、X射线衍射和电子探针等方法研究了氧气氛退火和淬火样品的氧化铝-二氧化硅相关系。莫来石的固溶体边界随着温度的升高而变化，并在1890°C和77.15wt%氧化铝的组成下连接。莫来石的熔点为189°C，具有在76.5和77.0重量%氧化铝之间的包封率。
The alumina-silica phase relations of samples annealed in oxygen and quenched were studied by optical microscopy, image analysis, X-ray diffraction, and the electron microprobe. The solid solution boundaries of mullite changed with increasing temperature and joined at 1890°C and a composition of 77.15 wt% alumina. The melting point of mullite was 189°C with a peritectic between 76.5 and 77.0 wi% alumina.
