Study on Properties of Al₂O₃ –CaO-Na₂CO₃ Slag System

Abstract:

Liquidus temperature, electrical conductivity and phase composition of Al₂O₃-CaO-Na₂CO₃ slag were studied in the paper. The results showed that the minimum value of liquidus temperature was 1429°C when the content of Na₂CO₃ was 11%. The Al₂O₃-CaO-Na₂CO₃ slag of lower liquidus temperature had higher electrical conductivity, and the electrical conductivity of Al₂O₃-CaO-Na₂CO₃ slag increased with the increase of temperature. The main phases of Al₂O₃-CaO-Na₂CO₃ slag are composed of CaAl₂O₄, Ca₃Al₁₀O₁₈, NaAlO₂ and Na₂CO₃. The addition of Na₂CO₃ is to be more effective for decreasing liquidus temperature and increasing electrical conductivity in the Al₂O₃-CaO-Na₂CO₃ slag system.
