Abstract

Vapor pressure of lead and lead chlorides from FeO_T-CaO-SiO₂-Al₂O₃ slag system was measured by using Knudsen effusion method. The results suggest that the vapor pressures of lead and lead chlorides increase with increasing temperature. For the slag systems without chlorine, the logarithm of vapor pressure (lnp) shows highly linear dependency on the reciprocal of temperature (1/T), and higher vapor pressure is observed in the condition where more metallic lead vapor is formed. In this case, the vapor pressure of lead increases with increasing slag basicity (w(CaO)/w(SiO₂)), increasing FeO content and w(Fe²⁺)/w(Fe³⁺) ratio. For the case of slag system with chlorine addition, the total pressures of PbCl₂ and PbCl increase with decreasing basicity and FeO content of slag.
