• In order to determine the phase diagram of the MnO–SiO2–CrOx system for PO2=2×10-6 Pa at 1873 K, one of the important information for the controlling of non-metallic inclusions (deoxidation products) formation during the stainless steel Si-deoxidation process, the following equilibrium experiments were conducted at 1873 K under controlled oxygen partial pressure, PO2:(I) Phase equilibria of the MnO–Cr2O3 binary system were measured as a function of PO2 (2×10-6–2×102Pa).(II) Phase equilibria of the MnO–SiO2–CrOx ternary system were measured for PO2=2×10-6Pa.Finally, the change in composition of inclusions during this process with increasing silicon addition was examined by using the determined phase diagram of this ternary system.
