The influence of TiC0.3N0.7 on viscosities of CaO-SiO2-MgO-Al2O3-TiO2 slags was investigated by the rotating cylinder method in this work. From the viscosity experimental results, it was found that the viscosity of the two-phase suspension system increased with increasing the volume fraction of TiC0.3N0.7 particle and decreased with increasing the rotation speed. The viscosity increased with the temperature decreasing and the relationship between viscosity and temperature could be described by the Arrhenius equation. However, temperature has little influence on the relative viscosity which is the ratio of solid–liquid mixture viscosity to pure liquid viscosity. The modified Einstein–Roscoe equation based on the present experimental values could well estimate the viscosity of TiC0.3N0.7 containing melts. The apparent volume of TiC0.3N0.7 was calculated to be 5.0–6.0 times of its real volume.
Key words: slag / suspension system / relative viscosity / TiO2 / TiC0.3N0.7
