Physical chemistry of TiO2-containing FeO-based slag should be valuable to understand the iron and steelmaking processes using iron sand. In the present work, the activity of each component was estimated for FetO-SiO22-TiO2-MOx (MOx=CaO, MgO, AlO1.5) melts by using regular solution model. The empirical equation to estimate the reduction rate of the same melts by CO gas was derived from the experimental data. The methodology of the estimation of thermodynamic and kinetic properties of TiO2-containing FeO-based slag was established.
