Helium Uses: Helium is widely used in military, scientific research, petrochemical, refrigeration, medical, semiconductor, pipeline leakage detection, superconductivity experiments, metal manufacturing, deep-sea diving, high-precision welding, and production of optoelectronic products.
Helium can also be used as a leak detector for high vacuum devices, atomic nuclear reactors, spaceships, etc. and as a shielding gas for welding of magnesium, zirconium, aluminum, titanium and other metals.
Helium is one of the rare and strategic materials that are indispensable for the development of national defense and high-tech industries. Helium-containing natural gas is still the only source of industrially produced helium. China's helium resources are quite poor, low in content, difficult to extract and high in cost.
Therefore, while protecting the limited helium resources, the research and development of advanced natural gas helium extraction technology is of great significance for improving the economy of helium production, guaranteeing the safety of helium for national use, and promoting the development of the natural gas helium extraction industry in China.

Helium is a chemical element whose chemical symbol is He, and its atomic number is 2. It is a colorless noble gas that emits a deep yellow light when discharged.
At room temperature, it is an extremely light, colorless, odorless, tasteless monatomic gas. Helium is the most difficult of all gases to liquefy and is the only substance that cannot be solidified at standard atmospheric pressure. Helium is chemically very inactive and in its normal state is very difficult to react with other substances.
