abstract = {Vanadium oxides were added to the existing GTOx database
because of its important role in the ferro-titanium
metallurgy as well as in petroleum coke gasification. The
CaO–FeO–Fe2O3–MgO–SiO2 system is a part of GTOx
database and is chosen because of the existence of
experimentally determined vanadium distributions between
vanadium ferroalloys and metallurgical slags. The
CaO–FeO–Fe2O3–MgO–SiO2–V2O3–V2O5 system
including all binary and ternary sub-systems was
thermodynamically assessed using all available experimental
data. Vanadium was introduced into the thermodynamic
description of solid solution phases such as MeO, Spinel,
Corundum and Ca2SiO4-α using available experimental
information. Particular attention was given to the phase
Spinel which forms the wide completely miscible solid
solution Fe3O4–FeV2O4–MgV2O4–MgFe2O4. The
thermodynamic description of the metallic vanadium
containing systems was taken from the SGTE alloy database.
With the knowledge about the complex behavior of vanadium in
slags as well as in liquid metal alloys it is possible to
calculate the vanadium distribution ratios (V)/[V] between
iron melts and slags in a wide range of temperatures and
compositions, corroborating the validity of the model under
reducing conditions. The additionally developed viscosity
model shows good agreement between the calculated and
experimental values in vanadium-containing slags.},
