摘要

进行了高温 H2 还原和熔化实验，以从月球碎屑模拟物中提取金属铁。从熔渣和液态铁界面的润湿性角度研究了添加氧化物后金属铁回收率的差异。钛铁矿、白云石和 Na2O-xSiO2 复合物被用作添加氧化物。通过对表面张力和界面张力计算得出的接触角进行评估，讨论了润湿性对铁回收的影响。结果证实，润湿性是影响铁颗粒在这些炉渣中凝聚的主要因素。

Evaluation of Wettability at Interface between Molten Slag and Liquid Fe on Recovery of Metallic Fe from Lunar Regolith

High-temperature H₂ reduction and melting experiments were conducted to extract metallic Fe from lunar regolith simulant. Differences in the recovery of metallic Fe with the addition of oxides were investigated in terms of the wettability at the interface between molten slag and liquid Fe. Ilmenite, albite, and Na₂O·xSiO₂ compounds were used as additive oxides. The effect of wettability on Fe recovery is discussed by evaluation of the contact angle obtained by calculations of surface tension and interfacial tension. The results confirmed that wettability is a major factor affecting coalescence of Fe particles in these slags.
