In this study, the isothermal section of a Cu 2 O–Al 2 O 3 –SiO 2 pseudo‐ternary phase diagram at 1150°C was analyzed by means of a scanning electronic microscope and powder X‐ray diffraction of the quenched samples qualitatively, and the compositions of the tie‐points of the tie‐planes as well as their regions were determined by in situ high‐temperature quantitative X‐ray diffraction analysis and energy‐dispersive X‐ray spectroscopy. Then, the isothermal section of the Cu 2 O–Al 2 O 3 –SiO 2 pseudo‐ternary phase diagram at 1150°C was constructed; it was found that the isothermal section is composed of two single liquid‐phase regions, five two‐phase regions, and six three‐phase regions.
