Viscosity of the CaO-CaF₂ System Containing Chromium Oxide

Abstract

Viscosity of the CaO-CaF₂-Cr₂O₃ system (15%<CaO<25%, 75%<CaF₂<85%, 0%<Cr₂O₃<10%) was measured by the vibrational resonant amplitude method. From the experimental data on slags viscosity as a function of temperature, liquidus temperatures were determined. Viscosities and liquidus temperatures were found to increase with an increase in the chromium oxide concentration in the slag.
