Abstract: Composition and temperature dependences of component activities in the melt system CaO . SiO2-CaO - Al2O3 . 2SiO2 were determined by means of the phase diagram as well as primary composition and temperature dependence of relative enthalpy of melts. Using the activities, composition and temperature dependences of Gibbs energy and entropy of mixing were calculated. On the basis of the course of these dependences it can be concluded that the melts of this subsystem behave like general solutions.
