Helium is the gas with the lowest boiling point on Earth, at minus 268.9°C. It plays a key role in superconducting magnets, supporting the development and operation of nuclear magnetic resonance imaging technology and particle accelerators.
In manufacturing; in aerospace engineering, helium is still an important component of rocket propellant. China is a helium-poor country, but demand accounts for 11% of the global total demand. In 2022, my country's helium dependence on foreign countries will exceed 95%.
