Experimental study of phase equilibria in the system PbO-ZnO-SiO2

Abstract

An experimental study on the ternary system PbO-ZnO-SiO 2 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-SiO 2 -CaO-FeO-Fe 2 O 3 , 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-SiO 2 in the temperature range 640 ЊC to 1400 ЊC (913 to 1673 K).

Experimental study of phase equilibria in the “FeO”-ZnO-(CaO + SiO2) system with the CaO/SiO2 weight ratio of 0.71 at metallic iron saturation

“…As reaction of the metallic by the present authors. [21][22][23][24][28][29][30][31][32][33][34][35][36][37][38][39] The experimental work on iron with zinc oxide in the slag proceeds, forming iron oxide, the Ca-Fe-Si-O-Zn system in equilibrium with metallic iron the bulk composition of the slag changes but remains in the is part of this wider research program.…”

Application of the Levitation Technique for Investigation of Metal Alloys and Phase Equilibria in Slags

“…In this test program the results from the levitation experiments were compared with results obtained using a wellestablished tube furnace equilibration/quenching/EPMA technique [11][12][13].…”

Experimental Study of Liquidus of the “FeO”‐SiO 2 ‐PbO Slags in Equilibrium with Air and with Metallic Lead

“…Most of the low order PbO-containing systems have been experimentally well characterized in air previously, in nineties [1][2][3][4][5][6], and most of those systems have oxides with fixed oxidation state so that changing PO2 would not affect results. The intermediate oxygen partial pressure conditions affect the equilibria in the systems with transition metals, in particular -iron-oxide-containing systems where Fe 2+ and Fe 3+ are always present.…”
