Aluminium et Mercure – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n

\n

Aluminium<\/h3>\n

L’aluminium est un m\u00e9tal blanc argent\u00e9, doux, non magn\u00e9tique et ductile du groupe du bore. En masse, l’aluminium repr\u00e9sente environ 8 % de la cro\u00fbte terrestre; c’est le troisi\u00e8me \u00e9l\u00e9ment le plus abondant apr\u00e8s l’oxyg\u00e8ne et le silicium et le m\u00e9tal le plus abondant dans la cro\u00fbte, bien qu’il soit moins courant dans le manteau ci-dessous.

Mercure<\/h3>\n

Mercure est commun\u00e9ment appel\u00e9 mercure et \u00e9tait autrefois appel\u00e9 hydrargyrum.\u00a0Le mercure est un \u00e9l\u00e9ment lourd et argent\u00e9 du bloc d, le mercure est le seul \u00e9l\u00e9ment m\u00e9tallique liquide dans des conditions standard de temp\u00e9rature et de pression.<\/p>\n<\/div>

Aluminium et Mercure – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Aluminium<\/a><\/h3>\n

L’aluminium et ses alliages sont largement utilis\u00e9s dans les applications a\u00e9rospatiales, automobiles, architecturales, lithographiques, d’emballage, \u00e9lectriques et \u00e9lectroniques.\u00a0C’est le principal mat\u00e9riau de construction de l’industrie a\u00e9ronautique tout au long de son histoire.\u00a0Environ 70% des cellules des avions civils commerciaux sont fabriqu\u00e9es \u00e0 partir d’alliages d’aluminium, et sans aluminium, l’aviation civile ne serait pas \u00e9conomiquement viable.\u00a0L’industrie automobile utilise d\u00e9sormais l’aluminium comme pi\u00e8ces moul\u00e9es de moteur, roues, radiateurs et de plus en plus comme pi\u00e8ces de carrosserie.\u00a0L’aluminium 6111 et l’alliage d’aluminium 2008 sont largement utilis\u00e9s pour les panneaux ext\u00e9rieurs de carrosserie automobile.\u00a0Les blocs-cylindres et les carters sont souvent coul\u00e9s en alliages d’aluminium.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Mercure<\/a><\/h3>\n

Le mercure est principalement utilis\u00e9 pour la fabrication de produits chimiques industriels ou pour des applications \u00e9lectriques et \u00e9lectroniques.\u00a0Cependant, en raison de sa toxicit\u00e9, de nombreuses utilisations du mercure sont en cours d’\u00e9limination ou sont en cours de r\u00e9vision.\u00a0Il est utilis\u00e9 dans certains thermom\u00e8tres, en particulier ceux qui sont utilis\u00e9s pour mesurer des temp\u00e9ratures \u00e9lev\u00e9es.\u00a0Le mercure forme facilement des alliages, appel\u00e9s amalgames, avec d’autres m\u00e9taux tels que l’or, l’argent et l’\u00e9tain.\u00a0La facilit\u00e9 avec laquelle il s’amalgame avec l’or le rend utile pour r\u00e9cup\u00e9rer l’or de ses minerais.\u00a0Les amalgames au mercure \u00e9taient \u00e9galement utilis\u00e9s dans les obturations dentaires.\u00a0Le mercure gazeux est utilis\u00e9 dans les lampes \u00e0 vapeur de mercure et certaines enseignes publicitaires de type \u00ab enseigne au n\u00e9on \u00bb et lampes fluorescentes.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
