1. Using high-purity helium gas with a low boiling point of 268.9 ℃, liquid helium can be used for ultra-low temperature cooling. High purity helium gas is indispensable in the widely studied applications of superconductors in fields such as maglev trains.
2. Due to its inert chemical properties and lighter weight than air, high-purity helium gas is commonly used as a filling gas in spacecraft or advertising balloons, and this use is also well-known.
3. High purity helium gas is widely used in mixed gases for respiration in the field of ocean development, as well as in the cooling of superconducting electromagnets in magnetic resonance imaging equipment in the medical field. It is widely used in military, scientific research, petrochemicals, refrigeration, medical, semiconductor, pipeline leak detection, superconducting experiments, metal manufacturing, deep-sea diving, high-precision welding, optoelectronic product production, etc.
4. Can be used for low-temperature cold sources and superconducting technology. It can also be used as a leak detector for high vacuum devices, nuclear reactors, spacecraft, and as a protective gas for welding metals such as magnesium, zirconium, aluminum, and titanium.
5. Used as a pressurized gas for transporting liquid propellants such as hydrogen and liquid oxygen on rockets and spacecraft. It is also used as a cleaning agent for atomic reactors, carrier gas for gas chromatography analysis, balloon inflation, protective gas for arc welding, mixed gas for diving, and filling gas for gas thermometers.
6. Due to its good permeability and non flammability, high-purity helium gas is also used in the vacuum leak detection industry, such as helium mass spectrometer leak detectors
