Abstract:	Experimental studies on phase equilibria in the multi-component system PbO-ZnO-CaO-SiO₂-FeO-Fe₂O₃ in air have been conducted to characterize the phase relations of a complex slag system used in the oxidation smelting of lead and in typical lead blast furnace sinters. The liquidus in two pseudoternary sections ZnO-“Fe₂O₃”-(PbO + CaO + SiO₂) with the CaO/SiO₂ weight ratio of 0.1 and the PbO/(CaO + SiO₂) weight ratio of 6.2, and with CaO/SiO₂ weight ratio of 0.6 and the PbO/(CaO + SiO₂) weight ratio of 4.3, have been constructed.
