Gaseous helium

Helium is a colorless, tasteless, odorless, nontoxic gas, poorly soluble in water. This gas is highly valued because it is used in many life spheres.

This noble gas – helium – has the second lowest density following hydrogen. Being completely inert even at high temperatures, it shows low solubility in molten metals, and has a sufficiently small atomic diameter, allowing the gas to penetrate into the smallest pores. Helium’s boiling point is at -269 ° C, what appears to be the lowest figure among all the substances.

In large quantities, helium is extracted from helium-rich natural gas sources, located only in some places around the world. Its specific properties make the gas an essential component in multiple industries such as a buoyant gas for hot-air balloons and airships, a shielding gas for welding, a tracer gas for leak detection or a carrier gas in gas chromatography. Other uses are as follows:

  • In the process of germanium and silicon crystal growing for transistors.
  • For some metals fabrication, such as titanium and zirconium.
  • In laser and fiber-optic equipment.
  • For deep diving and medical purposes, mixed with oxygen.
  • As an auxiliary gas for filling MRI scanners with liquid helium.
