摘要
Phase-equilibrium data and the liquidus for the system “MnO”-CaO-(Al2O3-SiO2) at a manganese-rich alloy saturation have been determined in the temperature range from 1423 to 1723 K. The results are presented in the form of a pseudoternary section “MnO”-CaO-(Al2O3 + SiO2) with an Al2O3/SiO2 weight ratio of 0.41. The following primary phases are present in the range of conditions investigated: 3Al2O3·2SiO2; SiO2; MnO·Al2O3·2SiO2; (Mn,Ca)O·SiO2; 2(Mn,Ca)O·SiO2; MnO·Al2O3; (Mn,Ca)O; α-2CaO·SiO2; α′-2CaO·SiO2; 2CaO·Al2O3·SiO2; CaO·SiO2, and CaO·Al2O3·2SiO2. The presence of alumina in this system is shown to have a significant effect on the liquidus compared to the system “MnO”-CaO-SiO2, leading to the stabilization of the anorthite and gehlenite phases.
