Abstract

The vapor pressures of zinc and its chloride from a FeO-CaO-SiO2-Al2O3 slag system were measured by Knudsen effusion method under the conditions with varying parameters such as temperature and slag composition. The results show that the vapor pressures of metallic Zn and ZnCl2 increase with increasing temperature. For ZnCl2, the logarithm of vapor pressure is a linear function of the reciprocal of temperature. The slag basicity exhibits the different effects on the vapor pressures of metallic Zn and ZnCl2. The former increases with increasing slag basicity, while the latter decreases. A high FeO content in the slag tends to increase the vapor pressures of metallic Zn and ZnCl2.
