On some corrections to paper 'CaO solubility and activity coefficient in molten salts CaCl2-x (x = 0, NaCl, KCl, SrCl2, BaCl2 and LiCl)' published in Thermochim. Acta, 2008, V. 470, No 1-2, pp. 105-107

Imperfections in the treatment of the experimental results (calculation of the activity coefficients) on CaO behavior in melts of CaCl2-x (x = 0, NaCl, KCl, SrCl2, BaCl2 and LiCl) compositions used in the above-mentioned paper caused their incorrectness. A primitive variant of isothermal saturation resulted in the overestimation of CaO solubility in the studied melts by, at least, 20%. Nevertheless, negative deviations from the ideality caused by strong interaction between CaO and CaCl2 (formation of compounds) were found. The strengthening of oxoacidic properties of constituent cations leads to increase of CaO solubility in the studied melts.
