Materials Refining for Solar Array Production on the Moon
Materials Refining for Solar Array Production on the Moon by Geoffrey A. Landis is a focused exploration published by Bibliolife DBA of Bibilio Bazaar II LLC in June 2013. This 28-page work delves into the essential raw materials—silicon, aluminum, and glass—necessary for the production of solar arrays on the lunar surface. The book outlines a proposed process sequence for extracting these materials from lunar regolith, utilizing fluorine brought to the moon in the form of potassium fluoride.
Readers will find a detailed examination of the methods involved in separating the required materials from lunar rock, including the electrolysis of potassium fluoride in a eutectic salt melt. The text describes the reduction of tetrafluorosilane to silicon through plasma reduction and the subsequent reactions that recover fluorine from residual compounds. This edition provides insights into the technical processes relevant to lunar resource utilization, contributing to the broader discourse in political science regarding space exploration and resource management.
Official synopsis Publisher
Silicon, aluminum, and glass are the primary raw materials that will be required for production of solar arrays on the moon. A process sequence is proposed for producing these materials from lunar regolith, consisting of separating the required materials from lunar rock with fluorine. The fluorine is brought to the moon in the form of potassium fluoride, and is liberated from the salt by electrolysis in a eutectic salt melt. Tetrafluorosilane produced by this process is reduced to silicon by a plasma reduction stage; the fluorine salts are reduced to metals by reaction with metallic potassium. Fluorine is recovered from residual MgF and CaF2 by reaction with K2O.
