Using the Knudsen effusion mass spectrometric method, the composition of vapour and the partial pressures of vapour species over melts of the CaOAl 2 O 3 system were studied for the temperature range 1833–2033 K. Thermodynamic functions of the CaOAl 2 O 3 system were obtained, and the negative deviations from ideal behaviour were illustrated. The dependence of the Gibbs energies of formation of the CaOAl 2 O 3 system on temperature and concentration of components was suggested.
