L’argon est le troisi\u00e8me gaz le plus abondant dans l’atmosph\u00e8re terrestre, \u00e0 0,934 % (9340 ppmv).\u00a0Il est plus de deux fois plus abondant que la vapeur d’eau (qui est en moyenne d’environ 4000 ppmv, mais varie consid\u00e9rablement), 23 fois plus abondant que le dioxyde de carbone (400 ppmv) et plus de 500 fois plus abondant que le n\u00e9on (18 ppmv).\u00a0L’argon est principalement utilis\u00e9 comme gaz de protection inerte dans le soudage et d’autres proc\u00e9d\u00e9s industriels \u00e0 haute temp\u00e9rature o\u00f9 des substances habituellement non r\u00e9actives deviennent r\u00e9actives;\u00a0par exemple, une atmosph\u00e8re d’argon est utilis\u00e9e dans les fours \u00e9lectriques \u00e0 graphite pour emp\u00eacher le graphite de br\u00fbler.<\/p>\n<\/div>

N\u00e9on<\/a><\/h3>\n

Le n\u00e9on est souvent utilis\u00e9 dans les enseignes et produit une lumi\u00e8re rouge\u00e2tre-orange incomparable.\u00a0Bien que les lampes \u00e0 tube avec d’autres couleurs soient souvent appel\u00e9es \u00ab\u00a0n\u00e9on\u00a0\u00bb, elles utilisent diff\u00e9rents gaz nobles ou des couleurs vari\u00e9es d’\u00e9clairage fluorescent.\u00a0Le n\u00e9on est \u00e9galement utilis\u00e9 pour fabriquer des indicateurs haute tension et des appareillages de commutation, des parafoudres, des \u00e9quipements de plong\u00e9e et des lasers.\u00a0Le n\u00e9on liquide est un r\u00e9frig\u00e9rant cryog\u00e9nique important.\u00a0Il a plus de 40 fois plus de puissance frigorifique par unit\u00e9 de volume que l’h\u00e9lium liquide et plus de 3 fois celle de l’hydrog\u00e8ne liquide.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Argon<\/a><\/h3>\n

Les principales applications de l’argon sont les suivantes\u00a0: lampes \u00e9lectriques comme gaz de remplissage, soudage, tubes \u00e0 d\u00e9charge, lasers \u00e0 argon et lasers \u00e0 colorant \u00e0 l’argon.\u00a0L’argon est principalement utilis\u00e9 comme gaz de protection inerte dans le soudage et d’autres proc\u00e9d\u00e9s industriels \u00e0 haute temp\u00e9rature o\u00f9 des substances habituellement non r\u00e9actives deviennent r\u00e9actives;\u00a0par exemple, une atmosph\u00e8re d’argon est utilis\u00e9e dans les fours \u00e9lectriques \u00e0 graphite pour emp\u00eacher le graphite de br\u00fbler.\u00a0L’argon est \u00e9galement utilis\u00e9 dans l’\u00e9clairage incandescent, fluorescent et autres tubes \u00e0 d\u00e9charge.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
