Product Description Helium is a colorless, tasteless, odorless noble gas with the chemical formula He that has an extremely low boiling and melting point and is the most difficult of all gases to liquefy. The chemical properties of helium are very inert, and it is difficult to react with other substances under normal circumstances. Because of these properties, helium is used in a wide variety of applications:
Helium is the second most abundant element in the universe, after hydrogen, and is found mostly in stars and planets. The main source of helium on Earth is natural gas, of which helium-rich hydrocarbon natural gas can contain up to 7.5% helium, which is 15,000 times that of air. However, global helium resources are chronically in short supply, with annual demand of about 200 million cubic meters, but annual production of only 170 million cubic meters. China has a low degree of research on helium resources, and its resources are unclear. At present, the supply of helium depends on imports for a long time |
