The thermodynamic properties of liquid melts in the Fe-S and Fe-S-metal systems

The thermodynamic properties of melts in the Fe-S and Fe-S-M systems were s tudied calorimetrically to determine the desulfurizing power of various d a nd f metals. Conclusions on the desulfurization activity of d and f metals in sulfur-containing iron-based melts were drawn. It was found that the add ition of some metals to sulfur-containing solutions caused substantial chan ges in their partial molar enthalpies. In Fe-S-M ternary system melts, the desulfurizing power of metals increased in the series Mo --> Cr --> Mn --> Nh --> Ta --> Ti --> Zr --> Hf --> La --> Ce.
