Arg\u00f4nio<\/span><\/h3>\n

O arg\u00f4nio \u00e9 o terceiro g\u00e1s mais abundante na atmosfera da Terra, com 0,934% (9340 ppmv).\u00a0\u00c9 duas vezes mais abundante que o vapor de \u00e1gua (que tem uma m\u00e9dia de cerca de 4.000 ppmv, mas varia muito), 23 vezes mais abundante que o di\u00f3xido de carbono (400 ppmv) e mais de 500 vezes mais abundante que o ne\u00f4nio (18 ppmv).\u00a0O arg\u00f4nio \u00e9 usado principalmente como g\u00e1s de prote\u00e7\u00e3o inerte em soldagem e outros processos industriais de alta temperatura, onde subst\u00e2ncias normalmente n\u00e3o reativas se tornam reativas;\u00a0por exemplo, uma atmosfera de arg\u00f4nio \u00e9 usada em fornos el\u00e9tricos de grafite para evitar que a grafite queime.<\/p>\n<\/div>

Krypton<\/span><\/h3>\n

Krypton \u00e9 um membro do grupo 18 (gases nobres) elementos.\u00a0Um g\u00e1s nobre incolor, inodoro e ins\u00edpido, o cript\u00f4nio ocorre em pequenas quantidades na atmosfera e \u00e9 frequentemente usado com outros gases raros em l\u00e2mpadas fluorescentes.<\/span><\/p>\n<\/div>

Arg\u00f4nio<\/span><\/a><\/h3>\n

As principais aplica\u00e7\u00f5es do arg\u00f4nio incluem o seguinte: l\u00e2mpadas el\u00e9tricas como g\u00e1s de enchimento, fins de soldagem, tubos de descarga, lasers de arg\u00f4nio e lasers de corante de arg\u00f4nio.\u00a0O arg\u00f4nio \u00e9 usado principalmente como g\u00e1s de prote\u00e7\u00e3o inerte em soldagem e outros processos industriais de alta temperatura, onde subst\u00e2ncias normalmente n\u00e3o reativas se tornam reativas;\u00a0por exemplo, uma atmosfera de arg\u00f4nio \u00e9 usada em fornos el\u00e9tricos de grafite para evitar que a grafite queime.\u00a0O arg\u00f4nio tamb\u00e9m \u00e9 usado em l\u00e2mpadas incandescentes, fluorescentes e outros tubos de descarga de g\u00e1s.<\/span><\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Krypton<\/span><\/a><\/h3>\n

As m\u00faltiplas linhas de emiss\u00e3o de Krypton fazem com que as descargas de g\u00e1s de krypton ionizado pare\u00e7am esbranqui\u00e7adas, o que, por sua vez, torna as l\u00e2mpadas \u00e0 base de krypton \u00fateis na fotografia como fonte de luz branca.\u00a0Krypton \u00e9 usado em alguns flashes fotogr\u00e1ficos para fotografia de alta velocidade.\u00a0Krypton tamb\u00e9m \u00e9 usado em t\u00e9cnicas de MRI\/CT.<\/span><\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
