摘      要：In accordance with the coexistence theory of slag structure and slag phase diagrams,the thermodynamic calculation models of MnO-TiO2 and FeO-Fe2 O3-TiO2 slag melts have been deduced. It is shown from the calculated results that, (1) the calculated mass action concentmtions NMno are in good agreement with the measured activities aMnO for MnO-TiO2 slag melt, and (2) the calculated oxidising capabilitg values NFetO are consistent with the obserred results aFeto for FeO-Fe2O3-TiO2 slag ***, the changes of mass action concentrations NFeO with the compositionsof MnO-FeO-TiO2 ternary slag system are estimated based on the thermodynamic data of binary slags.
