Abstract
The method of isoperibolic calorimetry was used for evaluating the energy state (heat capacity, enthalpy of slag formation) of slags of MnO-SiO₂-Me_xO_y (CaO, Al₂O₃, TiO₂) and welding fluxes of AN-348A, AN-60, ANTs-1, AN-26S, AN-47, AN-67A grades at 1923K. Proceeding from the experimental data on heat of mixing the values of activity of oxides of manganese and silicon in the MnO-SiO₂ system and also in slags on this base were determined.
Keywords: welding slags, thermodynamic investiga¬tions, heat of mixing, activity of components
