Uses Of Helium Gas and Liquid Helium

1. Uses Of Helium Gas and Liquid Helium Because liquid helium is a lightweight, inert gas, it can be used to fill various types of balloons, such as balloons used in rides. Liquid helium has also had medical uses, since it is used as the cooling medium for magnets, and processes used in MRI scanners and NMR spectrometers. Because of this, helium is used to give a lower temperature needed by superconducting magnets, like the ones used in most MRI scanners at hospitals. To take high-resolution images of organs and inner tissues, the machines used for MRI and NMR employ superconducting magnets, which require liquid helium to achieve cryogenic temperatures where they work. Liquid helium is used for cryogenics, as well as for superconducting magnet cooling, with its primary commercial use being in MRI scanners. Although it is not used directly as a rocket fuel, Helium Gas is used to scrub the propellant tanks clean of liquid hydrogen and oxygen used as propellant. Helium itself is also used to clean propellants and oxidizers from ground support equipment before launch, and for the pre-cooling of liquid hydrogen on spacecraft. Gas from Helium Gas Cylinder is used as a shielding agent in inert arc welding, to pressurize rocket tanks with liquid propellants, and in hypersonic wind tunnels. It may be used as the shielding gas for autogenous welding processes. Helium can be used in lasers, as even at high temperatures, the gas does not react or bond to other elements. Superconductors can work only when they are surrounded by extreme helium cold, and helium has been used in space for cooling satellite instruments and as fuel coolant in spacecraft. One way to make semiconductors, found in practically every electronic device today, requires liquid helium to cool magnets used in a way of making semiconductors. Helium is a treasured element, as it is characteristically used as a coolant. It is an inert gas, sense that it does not respond when exposed to some other chemicals or any elements.
