3 天之前 · 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.

2022年5月22日 · Helium is used as a cooling medium not only in nuclear reactors but also in magnetic scanners as well as cools space instruments. Helium is also used as a heat transfer within the nuclear reactors, and that is simply because it has a very high specific heat as well as a higher thermal conductivity.

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.

2015年6月15日 · Helium is used four different ways in the semiconductor manufacturing process: in a specialized cooling process, as a dilutant gas for plasma etching, as a carrier gas for deposition processes, and as a leak detector. All modern electronics, including video games, televisions, and even solar panels rely on semiconductors and therefore, helium.

2025年1月17日 · helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F). The boiling and freezing points of helium are lower than those of any other known substance.

Helium is classically used to fill balloons, but here are 10 uses for helium included in medicine, science and modern technology.

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.

2018年11月15日 · Helium is used for medicine, scientific research, arc welding, refrigeration, gas for aircraft, coolant for nuclear reactors, cryogenic research and detecting gas leaks. It is used for its cooling properties because of its boiling point being close to absolute zero.

What is helium used for, and why is it a strategic natural resource? Perhaps the most familiar use of helium is as a safe, non-flammable gas to fill party and parade balloons. However, helium is a critical component in many fields, including scientific research, medical technology, high-tech manufacturing, space exploration, and national defense.

Helium is the second element on the periodic table. It is a colourless and odourless gas yet it has a number of uses, some of which may surprise you! Helium gas is literally ‘lighter-than-air’ due to its extremely low density, which explains its most well-known use; decorative balloons.
