Phase equilibria in the CaO–SiO₂–CrO_x system were experimentally investigated at 1600°C and pO₂ of 10⁻¹⁰ to 10⁻¹¹ atm using the high-temperature isothermal equilibration/drop quenching/electron probe X-ray microanalysis technique. The constrained isothermal sections of the CaO–SiO₂–CrO_x system were constructed at 1600°C and pO₂ of 10⁻¹⁰ to 10⁻¹¹ atm based on the experimental results. The primary phase fields including cristobalite (SiO₂), larnite (Ca₂SiO₄), (Ca,Cr)Cr₂O₄, and corundum (Cr₂O₃) were determined. Simulations by thermodynamic software MTDATA, FactSage, and Thermo-Calc were compared with the present experimental results.
