The phase equilibrium relation of the Al2O3-SiO2 system was thermo-analytically investigated using a molybdenum resistance furnace with an argon atmosphere and a tungsten-tungsten 26% rhenium thermocouple (supplementary experiments were also made), and the phase diargam for the high aluminous region was presented. The composition of mullite with the highest melting point is 2Al2O3·SiO2 or very close to that value, and the mullite of the composition melts in-congruently at 1890±5°C, giving a liquid with a composition slightly less in Al2O3 content than that of the mullite. Other investigators’ results were interpreted on the basis of the results of the present investigation. In the present experiment an “unstable” growth of corundum was frequently observed.
