| description | A new method, combining KTH model with geometrical model (General solution
model by Chou) to estimate viscosity of some ternary silicate slags, was
proposed in this work. According to modified KTH model, viscous Gibbs free
energy for mixing of ternary slags was estimated by employing general
solution model. It was found that viscous Gibbs energy for mixing of ternary
system could be calculated using solely viscous Gibbs energy for mixing of
sub-binary systems. The viscosities of five ternary slags CaO-MnO-SiO2,
CaO-FeO-SiO2, FeO-MnO-SiO2, CaO-MgO-SiO2 and FeO-MgO-SiO2 were estimated in
the present work. A good agreement with available experimental data, with
mean deviation less than 20%, was achieved. The modified KTH model has
advantages with less model parameters and improved estimation ability by
comparison to original KTH model. |
