Phase equilibria in the ZnO-“CuO”-SiO system have been investigated at 1403-1948 K (1130-1675 °C) for oxide liquid in equilibrium with Cu-Zn metal (> 99% Cu) and solid oxide phases: (a) tridymite or cristobalite SiO; (b) willemite ZnSiO; (c) zincite ZnO; and (d) cuprite CuO. Two-liquid immiscibility range in the high-SiO slags has also been studied. High-temperature equilibration on primary phase (SiO, CuO), inert metal (platinum-iridium wire), or ceramic (AlO for high-CuO slags) substrates, followed by quenching and direct measurement of Zn, Cu, Si and possible impurities (Al, Pt, Ir) concentrations in the phases with the electron probe x-ray microanalysis (EPMA) has been used to accurately characterize the system in equilibrium with metal. All results are projected onto the ZnO-“CuO”-SiO plane for presentation purposes.

ZnO-“CuO0.5”和ZnO-“CuO0.5”-SiO2液相线与Cu-Zn金属平衡的实验液相线研究

已在 1403-1948 K (1130-1675 °C) 下研究了 ZnO-“CuO”-SiO 系统中与 Cu-Zn 金属（> 99% Cu）和固体氧化物相平衡的氧化物液体的相平衡：（a )鳞石英或方石英SiO；(b) 硅锌矿；(c) 锌矿氧化锌；(d) 赤铜矿CuO。还研究了高 SiO 渣中的两液不混溶范围。在主相（SiO、CuO）、惰性金属（铂-铱丝）或陶瓷（用于高 CuO 渣的 Al2O）基材上进行高温平衡，然后淬火并直接测量 Zn、Cu、Si 和可能的杂质（电子探针 X 射线微量分析 (EPMA) 中的 Al、Pt、Ir) 浓度已被用于准确表征与金属平衡的系统。出于演示目的，所有结果都投影到 ZnO-“CuO”-SiO 平面上。
