Effect of Titanium and Molybdenum Oxides on Viscosity and Electrical Conductivity of Oxide-Fluoride Slags

摘要

The effect of additives of titanium and molybdenum oxides on the viscosity and electrical conductivity of the Al_2O_3-CaO-CaF_2 oxide-fluoride slag melts at 1750-1950 K is investigated by vibration viscosimetry and the ac bridge method. Crystallization intervals are established depending on the variation in the TiO_2 and MoO_3 concentrations in the melts from 0 to 25%, and it is revealed that the majority charge carriers are calcium and fluorine ions. These data indicate the complex-forming character of the behavior of Ti and Mo in aluminum-calcium oxide-fluoride melts.
