However, since it costs too much to bring all building supplies from the earth, it is desirable to use lunar resources for the construction. The surface of the lunar is covered with regolith. The regolith is sand of many kinds of metallic oxide such as SiO2, Al2O3, CaO, MgO, FeO etc. Then, we can get metallic building supplies by reducing the regolith. The conventional electrolysis method (i.e., the Hall-Heroult process) is widely used in industry, but it is not suitable for application on the moon, as it requires carbon electrodes as the reducing agent, which does not exist on the lunar surface. In this study, we employed a laser plasma wind tunnel to reduce Al2O3.

As a reducing agent, hydrogen is mixed with the working gas of argon because the hydrogen derived from solar wind exists on the lunar surface.

The produced Al was accelerated to supersonic speeds by a convergent-divergent nozzle to prevent Al from recombining with oxygen. From the Al and argon line distributions in the flow direction, it was found that Al remained in the dissociated state. A water-cooled copper tube was inserted in the flow to collect Al.

内容記述 | For construction of a lunar base, huge amounts of building supplies are necessary. However, since it costs too much to bring all building supplies from the earth, it is desirable to use lunar resources for the construction. The surface of the lunar is covered with regolith. The regolith is sand of many kinds of metallic oxide such as SiO2, Al2O3, CaO, MgO, FeO etc. Then, we can get metallic building supplies by reducing the regolith. The conventional electrolysis method (i.e., the Hall-Heroult process) is widely used in industry, but it is not suitable for application on the moon, as it requires carbon electrodes as the reducing agent, which does not exist on the lunar surface. In this study, we employed a laser plasma wind tunnel to reduce Al2O3. The use of stationary plasma for alumina reduction enables a higher processing capacity than direct heating by a focused laser beam.
