Magn\u00e9sium<\/h3>\n

Le magn\u00e9sium est un solide gris brillant qui ressemble physiquement aux cinq autres \u00e9l\u00e9ments de la deuxi\u00e8me colonne (groupe 2 ou m\u00e9taux alcalino-terreux) du tableau p\u00e9riodique: tous les \u00e9l\u00e9ments du groupe 2 ont la m\u00eame configuration \u00e9lectronique dans la couche \u00e9lectronique externe et une structure cristalline similaire.

Le chlore est un gaz jaune-vert \u00e0 temp\u00e9rature ambiante. C’est un \u00e9l\u00e9ment extr\u00eamement r\u00e9actif et un agent oxydant puissant: parmi les \u00e9l\u00e9ments, il a la plus haute affinit\u00e9 \u00e9lectronique et la troisi\u00e8me \u00e9lectron\u00e9gativit\u00e9 la plus \u00e9lev\u00e9e, derri\u00e8re seulement l’oxyg\u00e8ne et le fluor.<\/p>\n<\/div>

Magn\u00e9sium et Chlore – Applications<\/h2>\n<\/div><\/div>\n
\n

Magn\u00e9sium<\/a><\/h3>\n

Le magn\u00e9sium est le troisi\u00e8me m\u00e9tal de structure le plus couramment utilis\u00e9, apr\u00e8s le fer et l’aluminium.[35] Les principales applications du magn\u00e9sium sont, dans l’ordre: les alliages d’aluminium, le moulage sous pression (alli\u00e9 au zinc), l’\u00e9limination du soufre dans la production de fer et d’acier, et la production de titane dans le proc\u00e9d\u00e9 Kroll. Les alliages de magn\u00e9sium sont utilis\u00e9s dans une grande vari\u00e9t\u00e9 d’applications structurelles et non structurelles. Les applications structurelles incluent les \u00e9quipements automobiles, industriels, de manutention, commerciaux et a\u00e9rospatiaux. Les alliages de magn\u00e9sium sont utilis\u00e9s pour les pi\u00e8ces qui fonctionnent \u00e0 des vitesses \u00e9lev\u00e9es et doivent donc \u00eatre l\u00e9gers pour minimiser les forces d’inertie. Les applications commerciales comprennent les outils portatifs, les ordinateurs portables, les bagages et les \u00e9chelles, les automobiles (par exemple, les volants et les colonnes, les cadres de si\u00e8ge, les bo\u00eetiers de transmission). Magnox (alliage), dont le nom est l’abr\u00e9viation de \u00abmagn\u00e9sium non oxydant\u00bb, est compos\u00e9 \u00e0 99 % de magn\u00e9sium et \u00e0 1 % d’aluminium, et est utilis\u00e9 dans le gainage des barres de combustible dans les r\u00e9acteurs nucl\u00e9aires magnox.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Chlore<\/a><\/h3>\n

Le chlore est utilis\u00e9 dans la fabrication d’une large gamme de produits de consommation, dont environ les deux tiers sont des produits chimiques organiques tels que le chlorure de polyvinyle (PVC), de nombreux interm\u00e9diaires pour la production de plastiques et d’autres produits finis qui ne contiennent pas l’\u00e9l\u00e9ment.\u00a0En tant que d\u00e9sinfectant courant, le chlore \u00e9l\u00e9mentaire et les compos\u00e9s g\u00e9n\u00e9rateurs de chlore sont utilis\u00e9s plus directement dans les piscines pour les maintenir hygi\u00e9niques.\u00a0Bien qu’elle soit peut-\u00eatre mieux connue pour son r\u00f4le dans la fourniture d’eau potable, la chimie du chlore contribue \u00e9galement \u00e0 fournir des mat\u00e9riaux de construction \u00e9conomes en \u00e9nergie, des composants \u00e9lectroniques, des fibres optiques, des cellules \u00e0 \u00e9nergie solaire, 93 % des produits pharmaceutiques vitaux, 86 % des compos\u00e9s phytosanitaires, des plastiques m\u00e9dicaux. , et beaucoup plus.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
