Abstract
A thermodynamic model is proposed for describing silicate melts in the associated solution approximation with allowance made for the formati on of various silicon-oxygen groups. The model predicts the compositio n and temperature dependences of the thermodynamic properties in the C aO-SiO2 and MnO-SiO2 melt systems with an accuracy comparable to the e xperimental error and adequately describes phase equilibria in these s ystems. The thermodynamic parameters of silica polymerization are foun d to be independent of the silicate melt.
