Argon provides an inert atmosphere in which welded metals will not oxidise. Appearance. Argon is a colourless, odourless gas that is totally inert to other substances. Uses. Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements.

Argon is a colourless and odourless gas present to a very small extent in the atmosphere. Argon is very inert (indeed it is referred to as one of the noble gases) and is not known to form true chemical compounds. It makes a good atmosphere for working with air-sensitive materials since it is heavier than air and less reactive than N 2.
Argon gas is used to fill conventional incandescent and fluorescent light bulbs. Argon is also used as an inert gas shield for arc welding and cutting, as blanket for the production of titanium and other reactive elements. It is used as a protective atmosphere for growing silicon and germanium crystals. Argon is considered to be non-toxic. Isotop.
Dec 11, 2023 · Argon plasma coagulation (APC), also called argon photocoagulation, is a medical procedure performed during a bronchoscopy, colonoscopy or upper endoscopy. Providers use it to treat a variety of conditions in your gastrointestinal system or lungs and airways. APC uses ionized gas and an electrical current to create blood clots or scars, which ...
Az argon a levegőnél nehezebb, színtelen, szagtalan nemesgáz, rendszáma 18, vegyjele: Ar. A Föld légkörének 0,93%-át alkotja, ezzel a légkörben előforduló harmadik leggyakoribb gáz. Legfontosabb kémiai tulajdonsága csekély reakcióképessége ( inert ).
How is argon produced? Industrially, argon gas is produced via the fractional distillation of liquid air in a cryogenic air separation unit, This procedure separates liquid nitrogen (boiling point: 77.3 K) from argon (boiling point: 87.3 K) and liquid oxygen (boiling point: 90.2 K). Every year about 700,000 tons of argon is produced around the ...
