Chlore et Baryum – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n

\n

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.

Baryum<\/h3>\n

Le baryum est le cinqui\u00e8me \u00e9l\u00e9ment du groupe 2 et est un m\u00e9tal alcalino-terreux doux et argent\u00e9.\u00a0En raison de sa grande r\u00e9activit\u00e9 chimique, le baryum ne se trouve jamais dans la nature en tant qu’\u00e9l\u00e9ment libre.\u00a0Les masses de fragments de fission les plus probables se situent autour des masses 95 (Krypton) et 137 (Baryum).<\/p>\n<\/div>

Chlore et Baryum – 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. En 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. Bien 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

\n

Baryum<\/a><\/h3>\n

Le baryum n’est pas un \u00e9l\u00e9ment largement utilis\u00e9.\u00a0La plupart sont utilis\u00e9s dans les fluides de forage pour les puits de p\u00e9trole et de gaz.\u00a0Il est \u00e9galement utilis\u00e9 en peinture et en verrerie.\u00a0Le baryum est \u00e9galement un \u00e9l\u00e9ment cl\u00e9 dans la production de supraconducteurs en c\u00e9ramique.\u00a0L’oxyde de cuivre et de baryum de lanthane, ou LBCO, a \u00e9t\u00e9 d\u00e9couvert en 1986 et a \u00e9t\u00e9 le premier supraconducteur \u00e0 haute temp\u00e9rature.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
