Experimental Study of Phase Equilibria in the System PbO-ZnO-SiO,

An experimental study on the ternary system PbO-ZnO-SiO2:, in air by high-temperature equilibration and quenching techniques followed by electron probe X-ray microanalysis was carried out as part of the wider research program on the six-component system PbO-ZnO-SiO2-CaO-FeO-Fe2O3, which combines experimental and thermodynamic computer modeling techniques to characterize zinc and lead industrial slags. Liquidus and solidus data were reported for all primary phase fields in the system PbO-ZnO-SiO2 in the temperature range 640 °C to 1400 °C (913 to 1673 K).
