The paper investigates the carbothermal reduction of JSC-1A lunar regolith simulant with activated carbon for metal and metalloid production. Thermogravimetry and surface characterization techniques were used to analyze reactions and volatile production. Elemental distributions and morphologies of Si, Fe, and Ti were observed post-experiment. This paper presents a thermodynamic and experimental study on the carbothermal reduction of the lunar regolith simulants, specifically JSC-1A. The study aims to evaluate the feasibility of extracting metals and metalloids from lunar regolith using carbothermal reduction processes. The research includes a detailed analysis of the chemical and mineralogical composition of JSC-1A, as well as experimental investigations under ultra-high vacuum conditions. The findings contribute to the understanding of resource utilization on the Moon and support future lunar exploration and colonization efforts.
