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.
