Study on Properties of Al₂O₃ -CaO-CaF₂ Slag System

Abstract:

Liquidus temperature, electrical conductivity and phase composition of Al₂O₃ -CaO-CaF₂ slag system were studied. The results showed that the liquidus temperature of the slag decreased with increasing CaF₂ content, and its electrical conductivity increased with increasing CaF₂ content and temperature. The liquidus temperature is 1468°C when the content of CaF₂ is 20%. Its phase composition are composed of CaAl₂O₄、Ca₂Al₃O₆F、Ca₂AlF₇ andAlF₃. When the content of CaF₂ is 10%, there are lots of CaAl₂O₄. The content of CaAl₂O₄ decreased with increasing CaF₂, but the content of Ca₂Al₃O₆F and Ca₂AlF₇ increased.
