Abstract

Activities of the components, the Gibbs energy of mixing, and the excess entropy of mixing have been calculated for the Ca<sub>2</sub>MgSi<sub>2</sub>O<sub>7</sub>-CaSiO<sub>3 </sub>system. The mole fractions of the components were calculated assuming that in the point of the formal component Ca<sub>2</sub>MgSi<sub>2</sub>O<sub>7</sub>, the molar mass of the quasi-real particle in the melt corresponds to its formula molar mass, whereas in the point of the formal component CaSiO<sub>3</sub> the molar mass of the quasi-real particle in the melt is 8.5 times higher than as corresponds to its formula. The fact that the enthalpy of mixing is zero whereas the excess entropy of mixing is non-zero suggests that Ca<sub>2</sub>MgSi<sub>2</sub>O<sub>7</sub>-CaSiO<sub>3</sub> melts behave as athermal solutions.
