Formatted abstract
The liquidus line in the FeOX corner of FeOXSiO2-CaO system and the effect by adding Al2O3 or MgO to this plain system on the liquidus line were experimentally investigated at 1523 K in a wide range of oxygen partial pressure between about 10-12 and about 10-4 atm and for given (mass% CaO=mass% SiO2) ratios in the system between 0 and about 1. It was found for the plain system that the liquidus line remarkably shifted toward the low FeOX-content region when the partial pressure of oxygen was increased from 10-10 to 10-8 atm. It was clarified that the addition of Al2O3 made the homogeneous region wide only in a strongly reducing atmosphere while the addition of MgO made the homogeneous liquid region remarkably narrow at all the oxygen partial pressures and all the (mass% CaO=mass% SiO2/ ratios investigated in the study.
