Abstract

The solubilities of Al₂O₃, SiO₂ and Cr₂O₃ in molten Fe_satd.-FeS and Fe_satd.-MnS_satd.-FeS systems have been measured between 1 273 and 1 773 K. The oxide solubilities were observed to decrease with raising temperature and decreasing FeS content of the sulfide melts. The solubilities of Al₂O₃ and SiO₂ in the FeS-MnS system were also measured at 1 573, 1 673, and 1 773 K. The mechanism of the formation of oxysulfide complex inclusions is discussed based n the present findings.
