They are released in their entirety when heated to temperatures above 700 ℃. The chlorine-3 gas is an efficient fuel for nuclear fusion reaction power generation, and the total amount of resources in lunar soil can reach 100-500 ten thousand tons. It was also calculated that about 6300 tons of hydrogen, 700 tons of nitrogen and 1600 tons of CO or CO2 gas could also be obtained from the lunar soil per 1 ton of chlorine-3 extracted. Natural iron, gold, silver, lead and zinc, copper ore particles, and cadmium sulfide ore formed by combining cadmium, zinc, iron, manganese and sulfur, and rhodium iodide which is not present on earth also exist in lunar soil.
The in-situ utilization of lunar water resources is significant for the establishment and durable operation of future lunar bases. For example, in situ harvested water ice may be treated to provide directly potable water required to maintain human survival in a lunar base. Meanwhile, oxygen generated by water electrolysis can be used as a consumable product of human respiratory metabolism in a lunar base, and generated hydrogen can also provide a pollution-free combustion agent for a rocket engine. Because the main environment of the moon water ice is a permanent shadow area of the polar region, the physical and chemical properties of the water ice can be obviously influenced by the extremely low temperature, high vacuum and other environmental conditions of the permanent shadow area, and the difficulty of water ice exploitation is further increased. Current research on lunar region water ice is mainly focused on the phase change characteristics of water ice, especially sublimation characteristics.
