Influence of TiO₂ on viscosity of aluminosilicate melts

Abstract

The structurally related viscosity model proposed in our previous studies has been extended to TiO₂ bearing melts. Experimental data on different systems containing CaO, MgO, Al₂O₃, TiO₂ and SiO₂ were assessed, and good agreement was achieved between the calculated and measured viscosities. It can be concluded that the addition of TiO₂ results in a decrease in viscosity, which is consistent with the experimental findings.
