Vapor pressure of zinc from the FetO-CaO-SiO2-Al2O3 slag system was measured by the Knudsen effusion method under conditions with varying parameters such as temperature, slag compositions, and initial contents of zinc and chlorine. In the thermodynamic estimations using thermodynamic parameters under the experimental temperature range, for slag samples without Cl addition, it suggests that metallic Zn is the only vapor species. In the case of Cl addition, gaseous ZnCl2 is predominant and the formation ratio of metallic Zn and FeCl2 can be neglected. In the measurements, the vapor pressures of metallic Zn and ZnCl2 increase with increasing temperature. For ZnCl2, the logarithm of vapor pressure (lnP) is a linear function of the reciprocal of temperature (1⁄T), while in the case of gaseous metallic Zn, a non-linear relationship is observed between lnP and 1⁄T. The slag basicity exhibits the different effects on the vapor pressures of metallic Zn and ZnCl2. The former increases with increasing the slag basicity, while the latter decreases. A high FeO content in the slag tends to increase the vapor pressure of metallic Zn and ZnCl2.
