Abstract The rate equation for the reaction of PbO with PbS in liquidstate at 850--1000℃ has been determined as dα/dt=4.73×10~6 exp (-190/RT)in which the activation en ergy E=190kJ/mol. In the solid-liquid reaction system of xPbO. SiO_2-PbS, the rate equation maybe formulated as following: dF(α)/dt=k′(t<20min)+k"(t>20min) (1000℃)where F(α)=α-(N°_(SiO_2/N°_(PbO))ln(1-α) The activities of PbO and SiO_2 in the silicate calculated from the rate dataare in good agreement with those measured thermodynamically.
