Oxyg\u00e8ne<\/h3>\n

L’oxyg\u00e8ne est un gaz r\u00e9actif incolore et inodore, l’\u00e9l\u00e9ment chimique de num\u00e9ro atomique 8 et le composant vital de l’air.\u00a0C’est un membre du groupe chalcog\u00e8ne du tableau p\u00e9riodique, un non-m\u00e9tal hautement r\u00e9actif et un agent oxydant qui forme facilement des oxydes avec la plupart des \u00e9l\u00e9ments ainsi qu’avec d’autres compos\u00e9s.\u00a0En masse, l’oxyg\u00e8ne est le troisi\u00e8me \u00e9l\u00e9ment le plus abondant dans l’univers, apr\u00e8s l’hydrog\u00e8ne et l’h\u00e9lium.

Aluminium<\/h3>\n

L’aluminium est un m\u00e9tal blanc argent\u00e9, doux, non magn\u00e9tique et ductile du groupe du bore. En masse, l’aluminium repr\u00e9sente environ 8 % de la cro\u00fbte terrestre; c’est le troisi\u00e8me \u00e9l\u00e9ment le plus abondant apr\u00e8s l’oxyg\u00e8ne et le silicium et le m\u00e9tal le plus abondant dans la cro\u00fbte, bien qu’il soit moins courant dans le manteau ci-dessous.<\/p>\n<\/div>

Oxyg\u00e8ne et Aluminium – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Oxyg\u00e8ne<\/a><\/h3>\n

Les utilisations courantes de l’oxyg\u00e8ne comprennent la production d’acier, de plastiques et de textiles, le brasage, le soudage et le d\u00e9coupage d’aciers et d’autres m\u00e9taux, le propulseur de fus\u00e9e, l’oxyg\u00e9noth\u00e9rapie et les syst\u00e8mes de survie dans les avions, les sous-marins, les vols spatiaux et la plong\u00e9e.\u00a0La fusion du minerai de fer en acier consomme 55 % de l’oxyg\u00e8ne produit commercialement.\u00a0Dans ce processus, l’oxyg\u00e8ne est inject\u00e9 \u00e0 travers une lance \u00e0 haute pression dans le fer fondu, qui \u00e9limine les impuret\u00e9s de soufre et l’exc\u00e8s de carbone sous forme d’oxydes respectifs, de dioxyde de soufre et de dioxyde de carbone.\u00a0L’absorption d’oxyg\u00e8ne de l’air est le but essentiel de la respiration, c’est pourquoi la suppl\u00e9mentation en oxyg\u00e8ne est utilis\u00e9e en m\u00e9decine.\u00a0Le traitement augmente non seulement les niveaux d’oxyg\u00e8ne dans le sang du patient, mais a pour effet secondaire de diminuer la r\u00e9sistance au flux sanguin dans de nombreux types de poumons malades, ce qui soulage la charge de travail sur le c\u0153ur.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Aluminium<\/a><\/h3>\n

L’aluminium et ses alliages sont largement utilis\u00e9s dans les applications a\u00e9rospatiales, automobiles, architecturales, lithographiques, d’emballage, \u00e9lectriques et \u00e9lectroniques.\u00a0C’est le principal mat\u00e9riau de construction de l’industrie a\u00e9ronautique tout au long de son histoire.\u00a0Environ 70% des cellules des avions civils commerciaux sont fabriqu\u00e9es \u00e0 partir d’alliages d’aluminium, et sans aluminium, l’aviation civile ne serait pas \u00e9conomiquement viable.\u00a0L’industrie automobile utilise d\u00e9sormais l’aluminium comme pi\u00e8ces moul\u00e9es de moteur, roues, radiateurs et de plus en plus comme pi\u00e8ces de carrosserie.\u00a0L’aluminium 6111 et l’alliage d’aluminium 2008 sont largement utilis\u00e9s pour les panneaux ext\u00e9rieurs de carrosserie automobile.\u00a0Les blocs-cylindres et les carters sont souvent coul\u00e9s en alliages d’aluminium.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
