摘要：
A thermodynamic model is proposed for describing silicate melts in the associated solution approximation with allowance made for the formation of various silicon-oxygen groups. The model predicts the composition and temperature dependences of the thermodynamic properties in the CaO-SiO2 and MnO-SiO2 melt systems with an accuracy comparable to the experimental error and adequately describes phase equilibria in these systems. The thermodynamic parameters of silica polymerization are found to be independent of the silicate melt.
