AI Technical Summary

Technical Problem

Existing methods for lunar soil metallurgy and oxygen production suffer from high costs and low efficiency. In particular, chemical methods require the transport of reducing agents from Earth, while electrolytic methods require large amounts of electricity and the anode materials are prone to corrosion, making it difficult to efficiently utilize lunar soil resources.

Method used

The lunar soil is electrolyzed using simulated solar wind. Electron and particle streams are separated by electric or magnetic fields, and oxidation and reduction reactions are carried out separately to generate metals and oxygen, thus avoiding high-temperature corrosion at the anode.

Benefits of technology

It enables efficient in-situ utilization of lunar resources, reduces transportation costs and power consumption, simplifies system structure, and avoids the need for consumable anode materials.

Abstract

The invention discloses a method for preparing metal and oxygen by smelting lunar soil through lunar surface solar wind, and belongs to the technical field of space metallurgy and oxygen generation. According to the method, hydrogen and argon mixed gas plasma is used for simulating solar wind particles, the simulated solar wind is used for electrolysis, an electric field or a magnetic field is used for deflection, so that current and particle flow in the solar wind are separated, and H < + > and He < + > are introduced into one side of a lunar soil molten oxide melt for an oxidation reaction; electrons are introduced into the other side of the molten oxide melt for a reduction reaction, protons and alpha particles at the oxidation reaction end act with oxygen ions at high temperature to generate water and oxygen, and electrons at the reduction reaction end act with metal ions to generate metal. According to the method provided by the invention, the solar wind resource can be utilized, meanwhile, the problem of high-temperature corrosion of the anode in the lunar soil electrolysis process is avoided, and in-situ utilization of lunar resources is realized.
