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.
- Helium 5.0 (high purity) – 99.999%;
- Helium 4.6 (grade “A”) – 99.995%;
- Helium 4.0 (grade “B”) – 99.99%;
- Industrial helium – 99.8%.
