 abstract={Basing on the data of Al2O3 and SiO2 thermodynamic acnvrties in SiO2-containing calcium aluminates of three formulae, CaO · Alz03, I 2CaO · 7Alz03 and 3Ca0 · Alz03 (shortly denoted as C1A" C12A7 and C3A1), at 1873K for the wide range of SiO2 mole fractions [!], we propose their activities expressed as functions of CaO contents provided there is no change in SiO2 mole fraction. The proposed relations allow to follow the change of the inclusions and steel composition during calcium treatment when calcium or calcium-silicon are added. An evolution of inclusion and steel compositions during calcium treatment was investigated starting from the partly modified inclusions C1A1-SiO2 with x;,02 = O.IO and 0.03. It was shown that the change of calcium aluminosilicates composition is slightly different for the pure calcium and calcium-silicon additions. With the calcium treatment the mole fraction of SiO2 in inclusions is decreasing less significant.},
