Abstract
The solubility of CO2 in Na2O-Fe2O3 and CaO-Fe2O3 systems and its effect on the viscosity have been measured to elucidate the behavior of CO2 in these melts. The quantitative analysis of CO2 content by the use of infra-red absorption spectra has been proposed for the slag systems. The solubility of CO2 in the CaO-Fe2O3 system and the silicate melt is less than 1 mol%CO2, while in the Na2O-Fe2O3 system it is 5-20 mol%CO2 due to the strong basicity of the melts. The effect of CO2 on the viscosity of Na2O-Fe2O3 system is almost the same as that of SiO2, which indicates that the constitution of CO2 in Na2O-Fe2O3 system can be assumed to be of a complex anion type species with a unit form of CO32− such as SiO44− in silicates.
