and liquidus temperature in the PbO-ZnO-CaO-SiO2-"Fe2O3" system, with the mass ratios of CaO/SiO2=1-1.6 and Fe/SiO2= 1.3-1.7, and 40% PbO and 8% ZnO, were carried out between 1273 and 1573 K. Slags were... between 1373 and 1473 K. The Ca/Pb silicate and magnetoplumbite phases are partially formed by an incongruent reaction. The experimental and thermodynamical results showed that the liquidus increased......
