The solubility of water vapor and the rate of water vapor dissolution in liquid CaO-SiO2-MgO and CaO-SiO2-TiO2 slags have been measured by a sampling method.
The solubilities of water in slags at 1 450°C were shown with water-vapor capacity, defined by log K'=log {(%H2O)s√PH2O}.
The water vapor dissolution in these liquid slags would be controlled by diffusion of H2O in the bulk slag the same as in the CaO-SiO2-Al2O3 system. The apparent diffusion coefficient of water vapor, DH2O, was evaluated and the effects of slag composition, such as basicity, MgO or TiO2 content and temperature on DH2O were discussed.
