In the present paper, the thermodynamic behaviour of transition metals, such as Cr, Ti, Nb and V in molten slags is systematically analysed based on a literature survey. These metals exist in molten slags with multi valences. Oxygen partial pressure, slag basicity, total content of each transition metal, content of each component in slag, and temperature are the influential factors on their thermodynamic properties in molten slags. Higher basicity and strong oxidative atmosphere are generally favourable for the stable existence of transition‐metal ions with higher oxidation states. Temperature is a factor that is less influential than the above‐mentioned ones. For a transition metal in molten slag, the concentration ratio of ions of different valences depends on the activity coefficient ratio of their oxides. The present paper summarizes the activity studies regarding the transition metal oxides in various molten slags. For chromium and titanium oxides, information on CaOSiO2 based systems is involved. For titanium oxides, its thermodynamic behaviour in MnOSiO2 based slags is introduced. For niobium and vanadium, the information in Na2OSiO2, CaOCaF2SiO2 systems is provided. Thermodynamic studies are described for Nb2O5MnOSiO2 molten slag equilibrated with liquid iron at 1828 K.
