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 calcium est un m\u00e9tal alcalino-terreux, c’est un m\u00e9tal jaune p\u00e2le r\u00e9actif qui forme une couche d’oxyde-nitrure sombre lorsqu’il est expos\u00e9 \u00e0 l’air.\u00a0Ses propri\u00e9t\u00e9s physiques et chimiques sont les plus similaires \u00e0 celles de ses homologues plus lourds, le strontium et le baryum.\u00a0C’est le cinqui\u00e8me \u00e9l\u00e9ment le plus abondant de la cro\u00fbte terrestre et le troisi\u00e8me m\u00e9tal le plus abondant, apr\u00e8s le fer et l’aluminium.<\/p>\n<\/div>

Magn\u00e9sium et Calcium – Applications<\/h2>\n<\/div><\/div>\n
\n
\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 \u00ab\u00a0magn\u00e9sium non oxydant\u00a0\u00bb, est compos\u00e9 \u00e0 99\u00a0% de magn\u00e9sium et \u00e0 1\u00a0% 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

\n

Calcium<\/a><\/h3>\n

La plus grande utilisation de calcium m\u00e9tallique est dans la sid\u00e9rurgie, en raison de sa forte affinit\u00e9 chimique pour l’oxyg\u00e8ne et le soufre.\u00a0Ses oxydes et sulfures, une fois form\u00e9s, donnent des inclusions d’aluminate de chaux liquide et de sulfure dans l’acier qui flottent.\u00a0Les compos\u00e9s de calcium sont utilis\u00e9s dans la fabrication d’insecticides, de peintures, de craie \u00e0 tableau noir, de textiles et de feux d’artifice.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
