Description:
Helium is a rare gas with the chemical formula He. It is colorless, odorless, and chemically inactive. It is difficult to react with other substances under normal conditions.

Typical Application:
Inflation Of Balloons And Airships
Helium, safer than hydrogen, inflates balloons and airships due to its low density, avoiding combustion or explosion risks.
‌Cryogenic Cooling ‌
Helium’s low boiling point is vital for cryogenic cooling in superconductivity and MRI, enabling ultra-low temperatures essential for medical and transport technologies.
‌Welding Protection ‌
Helium is used in welding for its stability, preventing metal oxidation and contamination, ensuring pure, mechanically sound welds.
‌Semiconductor Manufacturing ‌
In semiconductor production, helium is used to quickly cool silicon and other materials, control the rate of heat transfer, and improve production efficiency and product quality.
‌Diving ‌
When mixed with oxygen, helium can be used as a diving breathing gas to reduce the risk of “nitrogen narcosis” and improve diving safety and depth.
