利用Knudsen喷射法测试FeOT?CaO?SiO2?Al2O3渣系中铅及其氯化物的蒸汽压。结果显示该复杂体系中铅及其氯化物的蒸汽压随温度升高而升高。对于不含氯元素的渣系，铅的挥发气体种类为PbO 和金属Pb。二者蒸汽压的对数(lnp)与温度的倒数(1/T)之间呈良好的线性关系。金属 Pb 蒸汽形成比例越高，总的蒸汽压越高。铅的蒸汽压随FeOT?CaO?SiO2?Al2O3渣系碱度的升高、随FeO含量及w(Fe2+)/w(Fe3+)比例的升高而升高。对于含有Cl元素的渣系，铅的挥发气体种类为PbCl2和PbCl，二者总的蒸汽压随渣碱度及FeO含量的降低而升高。

Vapor pressure of lead and lead chlorides from FeOT?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 andw(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.
