Niobium<\/h3>\n

Le niobium est un m\u00e9tal de transition mou, gris et ductile, que l’on trouve souvent dans les min\u00e9raux pyrochlore (la principale source commerciale de niobium) et la columbite.<\/p>\n<\/div>

\u00c9tain<\/h3>\n

L’\u00e9tain est un m\u00e9tal post-transition du groupe 14 du tableau p\u00e9riodique.\u00a0Il est obtenu principalement \u00e0 partir de la cassit\u00e9rite min\u00e9rale, qui contient du dioxyde d’\u00e9tain.\u00a0Le premier alliage utilis\u00e9 \u00e0 grande \u00e9chelle \u00e9tait le bronze, compos\u00e9 d’\u00e9tain et de cuivre, d\u00e8s 3000 av.<\/p>\n<\/div>

Niobium et \u00c9tain – Applications<\/h2>\n<\/div><\/div>\n

\n

Niobium<\/a><\/h3>\n

La consommation de niobium est domin\u00e9e par son utilisation comme additif \u00e0 l’acier faiblement alli\u00e9 \u00e0 haute r\u00e9sistance et \u00e0 l’acier inoxydable pour les ol\u00e9oducs et gazoducs, les carrosseries de voitures et de camions, les exigences architecturales, les aciers \u00e0 outils, les coques de navires, les voies ferr\u00e9es.\u00a0Cependant, il existe un certain nombre d’autres applications pour le niobium m\u00e9tallique et ses compos\u00e9s.\u00a0Bien que le niobium ait de nombreuses applications, la majorit\u00e9 est utilis\u00e9e dans la production d’acier de construction de haute qualit\u00e9.\u00a0La deuxi\u00e8me plus grande application du niobium concerne les superalliages \u00e0 base de nickel.\u00a0Les alliages niobium-\u00e9tain sont utilis\u00e9s comme aimants supraconducteurs.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\u00c9tain<\/a><\/h3>\n

La principale application de l’\u00e9tain est la fabrication de fer-blanc (t\u00f4le d’acier rev\u00eatue d’\u00e9tain), qui repr\u00e9sente environ 40 % de la consommation mondiale totale d’\u00e9tain.\u00a0L’\u00e9tain adh\u00e8re facilement au fer et \u00e0 l’acier pour pr\u00e9venir la corrosion.\u00a0Les r\u00e9cipients en acier \u00e9tam\u00e9 sont largement utilis\u00e9s pour la conservation des aliments, ce qui constitue une grande partie du march\u00e9 de l’\u00e9tain m\u00e9tallique.\u00a0L’\u00e9tamage est le processus de rev\u00eatement mince de feuilles de fer forg\u00e9 ou d’acier avec de l’\u00e9tain, et le produit r\u00e9sultant est connu sous le nom de fer-blanc.\u00a0Le terme est \u00e9galement largement utilis\u00e9 pour les diff\u00e9rents processus de rev\u00eatement d’un m\u00e9tal avec de la soudure avant le soudage.\u00a0Il existe deux proc\u00e9d\u00e9s d’\u00e9tamage des plaques noires : le trempage \u00e0 chaud et la galvanoplastie.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
