\n
\"\"<\/div>
\n

Rhodium<\/h3>\n

Le rhodium est un m\u00e9tal de transition rare, blanc argent\u00e9, dur, r\u00e9sistant \u00e0 la corrosion et chimiquement inerte.\u00a0C’est un m\u00e9tal noble et un membre du groupe du platine.<\/p>\n<\/div>

Or<\/h3>\n

L’or est un m\u00e9tal jaune vif, l\u00e9g\u00e8rement rouge\u00e2tre, dense, mou, mall\u00e9able et ductile.\u00a0L’or est un m\u00e9tal de transition et un \u00e9l\u00e9ment du groupe 11.\u00a0C’est l’un des \u00e9l\u00e9ments chimiques les moins r\u00e9actifs et il est solide dans des conditions standard.\u00a0On pense que l’or a \u00e9t\u00e9 produit lors de la nucl\u00e9osynth\u00e8se des supernovas, \u00e0 partir de la collision d’\u00e9toiles \u00e0 neutrons.<\/p>\n<\/div>

Rhodium et Or – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Rhodium<\/a><\/h3>\n

L’utilisation principale de l’\u00e9l\u00e9ment (environ 80% de la production mondiale de rhodium) est l’un des catalyseurs des convertisseurs catalytiques \u00e0 trois voies des automobiles.\u00a0Parce que le m\u00e9tal rhodium est inerte contre la corrosion et la plupart des produits chimiques agressifs, et en raison de sa raret\u00e9, le rhodium est g\u00e9n\u00e9ralement alli\u00e9 au platine ou au palladium et appliqu\u00e9 dans des rev\u00eatements r\u00e9sistants aux hautes temp\u00e9ratures et \u00e0 la corrosion.\u00a0Dans les r\u00e9acteurs nucl\u00e9aires, les d\u00e9tecteurs \u00e0 base de rhodium sont souvent utilis\u00e9s pour mesurer le flux neutronique dans le c\u0153ur.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Or<\/a><\/h3>\n

L’or est largement utilis\u00e9 en joaillerie, soit sous sa forme pure, soit sous forme d’alliage.\u00a0Environ 75% de tout l’or produit est utilis\u00e9 dans l’industrie de la bijouterie.\u00a0L’or pur est trop mou pour r\u00e9sister aux contraintes appliqu\u00e9es \u00e0 de nombreux bijoux.\u00a0Les artisans ont appris que l’alliage de l’or avec d’autres m\u00e9taux tels que le cuivre, l’argent et le platine augmenterait sa durabilit\u00e9.\u00a0Le terme \u00ab carat \u00bb indique la quantit\u00e9 d’or pr\u00e9sente dans un alliage.\u00a024 carats est de l’or pur, mais il est tr\u00e8s doux.\u00a0Les alliages d’or 18 et 9 carats sont couramment utilis\u00e9s car ils sont plus durables.\u00a0La grande mall\u00e9abilit\u00e9, la ductilit\u00e9, la r\u00e9sistance \u00e0 la corrosion et \u00e0 la plupart des autres r\u00e9actions chimiques et la conductivit\u00e9 de l’\u00e9lectricit\u00e9 de l’or ont conduit \u00e0 son utilisation continue dans les connecteurs \u00e9lectriques r\u00e9sistants \u00e0 la corrosion dans tous les types d’appareils informatis\u00e9s (sa principale utilisation industrielle).\u00a0L’or est \u00e9galement utilis\u00e9 dans le blindage infrarouge,\u00a0production de verre color\u00e9, dorure \u00e0 la feuille et restauration dentaire.\u00a0Seuls 10\u00a0% de la consommation mondiale d’or neuf produit sont destin\u00e9s \u00e0 l’industrie, mais l’utilisation industrielle la plus importante de l’or neuf est de loin la fabrication de connecteurs \u00e9lectriques sans corrosion dans les ordinateurs et autres appareils \u00e9lectriques.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
