Chlore<\/h3>\n

Le chlore est un gaz jaune-vert \u00e0 temp\u00e9rature ambiante. C’est un \u00e9l\u00e9ment extr\u00eamement r\u00e9actif et un agent oxydant puissant: parmi les \u00e9l\u00e9ments, il a la plus haute affinit\u00e9 \u00e9lectronique et la troisi\u00e8me \u00e9lectron\u00e9gativit\u00e9 la plus \u00e9lev\u00e9e, derri\u00e8re seulement l’oxyg\u00e8ne et le fluor.

C\u00e9sium<\/h3>\n

Le c\u00e9sium est un m\u00e9tal alcalin doux et argent\u00e9 avec un point de fusion de 28,5\u00b0C, ce qui en fait l’un des cinq seuls m\u00e9taux \u00e9l\u00e9mentaires liquides \u00e0 ou pr\u00e8s de la temp\u00e9rature ambiante. Le c\u00e9sium a des propri\u00e9t\u00e9s physiques et chimiques similaires \u00e0 celles du rubidium et du potassium.<\/p>\n<\/div>

Chlore et C\u00e9sium – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Chlore<\/a><\/h3>\n

Le chlore est utilis\u00e9 dans la fabrication d’une large gamme de produits de consommation, dont environ les deux tiers sont des produits chimiques organiques tels que le chlorure de polyvinyle (PVC), de nombreux interm\u00e9diaires pour la production de plastiques et d’autres produits finis qui ne contiennent pas l’\u00e9l\u00e9ment.\u00a0En tant que d\u00e9sinfectant courant, le chlore \u00e9l\u00e9mentaire et les compos\u00e9s g\u00e9n\u00e9rateurs de chlore sont utilis\u00e9s plus directement dans les piscines pour les maintenir hygi\u00e9niques.\u00a0Bien qu’elle soit peut-\u00eatre mieux connue pour son r\u00f4le dans la fourniture d’eau potable, la chimie du chlore contribue \u00e9galement \u00e0 fournir des mat\u00e9riaux de construction \u00e9conomes en \u00e9nergie, des composants \u00e9lectroniques, des fibres optiques, des cellules \u00e0 \u00e9nergie solaire, 93 % des produits pharmaceutiques vitaux, 86 % des compos\u00e9s phytosanitaires, des plastiques m\u00e9dicaux. , et beaucoup plus.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

C\u00e9sium<\/a><\/h3>\n

La plus grande utilisation actuelle de c\u00e9sium non radioactif est dans les fluides de forage au formiate de c\u00e9sium pour l’industrie p\u00e9troli\u00e8re extractive.\u00a0Ils sont \u00e9galement utilis\u00e9s pour fabriquer du verre optique sp\u00e9cial, comme promoteur de catalyseur, dans des tubes \u00e0 vide et dans des \u00e9quipements de surveillance des rayonnements.\u00a0L’une de ses utilisations les plus importantes est dans \u00abl’horloge au c\u00e9sium\u00bb (horloge atomique).\u00a0Ces horloges sont une partie essentielle des r\u00e9seaux Internet et de t\u00e9l\u00e9phonie mobile, ainsi que des satellites du syst\u00e8me de positionnement global (GPS).\u00a0Le c\u00e9sium-137 est un radio-isotope couramment utilis\u00e9 comme \u00e9metteur gamma dans les applications industrielles.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
