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.

Le plomb est un m\u00e9tal lourd plus dense que la plupart des mat\u00e9riaux courants.\u00a0Le plomb est mou et mall\u00e9able, et a un point de fusion relativement bas.\u00a0Le plomb est largement utilis\u00e9 comme \u00e9cran gamma.\u00a0Le principal avantage du blindage en plomb r\u00e9side dans sa compacit\u00e9 en raison de sa densit\u00e9 plus \u00e9lev\u00e9e.\u00a0Le plomb a le num\u00e9ro atomique le plus \u00e9lev\u00e9 de tous les \u00e9l\u00e9ments stables et conclut trois cha\u00eenes de d\u00e9sint\u00e9gration majeures d’\u00e9l\u00e9ments plus lourds.<\/p>\n<\/div>

\u00c9tain et Plomb – Applications<\/h2>\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. L’\u00e9tain adh\u00e8re facilement au fer et \u00e0 l’acier pour pr\u00e9venir la corrosion. Les 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. L’\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. Le 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. Il 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

Plomb<\/a><\/h3>\n

Le plomb m\u00e9tallique poss\u00e8de plusieurs propri\u00e9t\u00e9s m\u00e9caniques utiles, notamment une densit\u00e9 \u00e9lev\u00e9e, un point de fusion bas, une ductilit\u00e9 et une inertie relative.\u00a0Le plomb est largement utilis\u00e9 pour les batteries de voiture, les pigments, les munitions, les gaines de c\u00e2ble, les poids de levage, les ceintures de poids pour la plong\u00e9e, le verre au cristal au plomb, la radioprotection et dans certaines soudures.\u00a0La plus grande utilisation de plomb au d\u00e9but du 21e si\u00e8cle concerne les batteries au plomb-acide.\u00a0Le plomb des batteries ne subit aucun contact direct avec les humains, il y a donc moins de probl\u00e8mes de toxicit\u00e9.\u00a0Le plomb est utilis\u00e9 dans les c\u00e2bles \u00e9lectriques \u00e0 haute tension comme mat\u00e9riau de gaine pour emp\u00eacher la diffusion de l’eau dans l’isolant;\u00a0cette utilisation diminue avec l’\u00e9limination progressive du plomb.\u00a0Un plomb est largement utilis\u00e9 comme \u00e9cran gamma.\u00a0Le principal avantage du blindage en plomb r\u00e9side dans sa compacit\u00e9 en raison de sa densit\u00e9 plus \u00e9lev\u00e9e.\u00a0En revanche, l’uranium appauvri est beaucoup plus efficace en raison de son Z plus \u00e9lev\u00e9.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
