Mangan\u00e8se<\/h3>\n

Le mangan\u00e8se est un m\u00e9tal avec d’importantes utilisations dans les alliages m\u00e9talliques industriels, en particulier dans les aciers inoxydables.

Mangan\u00e8se<\/a><\/h3>\n

Le mangan\u00e8se est un agent d’alliage important.\u00a0Pr\u00e8s de 90 % du mangan\u00e8se produit annuellement est utilis\u00e9 dans la production d’acier.\u00a0Dans les aciers, le mangan\u00e8se am\u00e9liore les qualit\u00e9s de laminage et de forgeage, ainsi que la r\u00e9sistance, la t\u00e9nacit\u00e9, la rigidit\u00e9, la r\u00e9sistance \u00e0 l’usure, la duret\u00e9 et la trempabilit\u00e9.\u00a0La deuxi\u00e8me plus grande application du mangan\u00e8se concerne les alliages d’aluminium.\u00a0L’aluminium avec environ 1,5% de mangan\u00e8se a une r\u00e9sistance accrue \u00e0 la corrosion gr\u00e2ce \u00e0 des grains qui absorbent les impuret\u00e9s qui conduiraient \u00e0 la corrosion galvanique.\u00a0Le mangan\u00e8se peut \u00eatre transform\u00e9 en de nombreux compos\u00e9s utiles.\u00a0Par exemple, l’oxyde de mangan\u00e8se, qui peut \u00eatre utilis\u00e9 dans les engrais et la c\u00e9ramique.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Zinc<\/a><\/h3>\n

Le zingage r\u00e9sistant \u00e0 la corrosion du fer (galvanisation \u00e0 chaud) est la principale application du zinc.\u00a0Le rev\u00eatement de l’acier constitue la plus grande utilisation unique du zinc, mais il est utilis\u00e9 en gros tonnages dans les pi\u00e8ces moul\u00e9es en alliage de zinc, sous forme de poussi\u00e8re et d’oxyde de zinc, et dans les produits en zinc corroy\u00e9.\u00a0L’acier galvanis\u00e9 est simplement de l’acier au carbone recouvert d’une fine couche de zinc.\u00a0Le zinc prot\u00e8ge le fer en se corrodant d’abord, mais le zinc se corrode beaucoup moins vite que l’acier.\u00a0D’autres applications concernent les batteries \u00e9lectriques, les petites pi\u00e8ces moul\u00e9es non structurelles et les alliages tels que le laiton.\u00a0Une vari\u00e9t\u00e9 de compos\u00e9s de zinc sont couramment utilis\u00e9s, tels que le carbonate de zinc et le gluconate de zinc (comme compl\u00e9ments alimentaires), le chlorure de zinc (dans les d\u00e9odorants), la pyrithione de zinc (shampoings antipelliculaires), le sulfure de zinc (dans les peintures luminescentes) et le dim\u00e9thylzinc ou le di\u00e9thylzinc. au laboratoire biologique.\u00a0Un \u00e9l\u00e9ment cl\u00e9 du monde des mat\u00e9riaux modernes dans lequel se trouve le zinc est le recyclage.\u00a0Le zinc, comme tous les m\u00e9taux (et contrairement aux mat\u00e9riaux synth\u00e9tiques) peut \u00eatre recycl\u00e9 ind\u00e9finiment sans d\u00e9gradation.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
