Abstract:
Experimental studies on the phase equilibrium and the liquidus isotherms for the CaO-SiO2-PbO-ZnO-FeO-Fe2O3 system with CaO/SiO2 mass ratio from 1.0 to 1.6 and Fe/SiO2 mass ratio from 1.1 to 1.7 were carried out in the temperature range from 1273 to 1573 K. The results are presented in the form of pseudoternary sections “Fe2O3â€-ZnO-(PbO+CaO+SiO2). The X-Ray and SEM-EDS results showed that the slag compositions of this study are in the spinel franklinite (ZnFe2O4) primary phase field. Hardystonite (Ca2ZnSiO7) and calcium and lead silicates are formed between 1100°C and 1200 °C. The results obtained from experimental and FACTSage calculations showed that increasing the CaO/SiO2 ratio for Fe/SiO2 = 1.1 to 1.7 decreases the liquidus temperature.
