1. High purity helium gas can be used as a propellant and booster for rocket liquid fuel, and is widely used in missiles, spacecraft, and supersonic aircraft

2. Helium is used as a protective gas during smelting and welding, which is very important in shipbuilding, as well as in the manufacturing of aircraft, spacecraft, rockets, and weapons.

3. High purity helium gas has excellent permeability and is used for cooling nuclear reactors, leak detection of pipelines, electronic and electrical devices in rockets and nuclear reactors.

4. High purity helium is a gas with ideal gas properties and is an ideal gas for vapor pressure thermometers at extremely low temperatures.

5. High purity helium has low mass density and weight density, and is not flammable. It can be used to fill light bulbs, neon tubes, and is also an ideal gas for balloons and airships.

6. Liquid helium can achieve low temperatures close to -273 ℃ and is used to manufacture superconducting devices.

7. High purity helium is an inert gas with lower solubility in blood compared to nitrogen, resulting in lower anesthetic properties. Therefore, high-purity helium is often mixed with oxygen.
