Helium is an inert gas due to which it is used in maintaining a protective atmosphere such as in the case of production of titanium and zirconium, growing germanium and silicon crystals, and also, in gas chromatography.
Helium is used as an inert-gas atmosphere for welding metals such as aluminum; in rocket propulsion (to pressurize fuel tanks, especially those for liquid hydrogen, because only helium is still a gas at liquid-hydrogen temperature); in meteorology (as a lifting gas for instrument-carrying balloons); in cryogenics (as a coolant because liquid ...
Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table.
Helium is classically used to fill balloons, but here are 10 uses for helium included in medicine, science and modern technology.
What is helium used for, and where does it come from? Learn facts about this noble gas, including how it causes balloons to float, its surprising uses in medicine and exploration, and how its...
Uses. Helium is used as a cooling medium for the Large Hadron Collider (LHC), and the superconducting magnets in MRI scanners and NMR spectrometers. It is also used to keep satellite instruments cool and was used to cool the liquid oxygen and hydrogen that powered the Apollo space vehicles.
Helium, the second most abundant element in the universe, is a colorless, odorless gas. It possesses unique properties that make it ideal for modern technological advances, such as semiconducting. Some of the everyday uses of helium include party balloons, car airbags, laser scanning and more.
What is helium used for, and where does it come from? Learn facts about this noble gas, including how it causes balloons to float, its surprising uses in medicine and exploration, and how its limited availability on Earth could affect science and industry.
Helium is used as powder carrier gas for fast thermal spraying (sometimes known as metal spraying), a versatile industrial process used for applying protective coatings, and repairing or enhancing the properties of various materials and components.
Explore the versatile world of Helium, the second most abundant element in the universe. Learn about its physical and chemical properties, historical background, and varied applications in healthcare, industry, and everyday life.
