Audited Supplier Helium gas is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, and non-toxic gas that belongs to the noble gas group on the periodic table. Helium is the second lightest element in the universe and the second most abundant element after hydrogen.
Helium is known for its low boiling point, which is the reason it remains a gas at normal temperatures and pressures. It has the lowest boiling and melting points among all the elements. Because of its low density, helium is lighter than air, which makes it useful for various applications.
One of the most well-known uses of helium is in filling balloons and airships. The buoyancy provided by helium allows objects to float in the air. Helium-filled balloons are commonly used for celebrations, scientific experiments, and even in some airships and blimps.
Helium is also widely used in cryogenics and as a cooling medium in various industries. Its extremely low temperature, close to absolute zero, makes it suitable for cooling superconducting magnets in magnetic resonance imaging (MRI) machines, particle accelerators, and other scientific equipment.
Furthermore, helium is used in various welding processes to shield the weld area from atmospheric gases and prevent oxidation. It is also employed in the production of semiconductors and fiber optics, where a controlled and inert atmosphere is necessary.
Despite its abundance in the universe, helium is relatively scarce on Earth. It is mainly obtained as a byproduct during the extraction of natural gas. However, helium is a non-renewable resource, and its supply is limited. Therefore, it is important to use helium efficiently and consider alternative methods or recycling to meet the demand.
In recent years, there have been concerns about the depletion of helium reserves and its impact on various industries. Efforts are being made to conserve helium and find alternative sources or develop new technologies to address the potential shortage.
