Fluor et Calcium – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n

\"\"<\/div>
\n

Fluor<\/h3>\n

Le fluor est l’halog\u00e8ne le plus l\u00e9ger et existe sous forme de gaz diatomique jaune p\u00e2le hautement toxique dans des conditions standard. En tant qu’\u00e9l\u00e9ment le plus \u00e9lectron\u00e9gatif, il est extr\u00eamement r\u00e9actif: presque tous les autres \u00e9l\u00e9ments, y compris certains gaz nobles, forment des compos\u00e9s avec le fluor.

\n

Calcium<\/h3>\n

Le calcium est un m\u00e9tal alcalino-terreux, c’est un m\u00e9tal jaune p\u00e2le r\u00e9actif qui forme une couche d’oxyde-nitrure sombre lorsqu’il est expos\u00e9 \u00e0 l’air.\u00a0Ses propri\u00e9t\u00e9s physiques et chimiques sont les plus similaires \u00e0 celles de ses homologues plus lourds, le strontium et le baryum.\u00a0C’est le cinqui\u00e8me \u00e9l\u00e9ment le plus abondant de la cro\u00fbte terrestre et le troisi\u00e8me m\u00e9tal le plus abondant, apr\u00e8s le fer et l’aluminium.<\/p>\n<\/div>

Fluor et Calcium – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Fluor<\/a><\/h3>\n

En raison des frais de raffinage du fluor pur, la plupart des applications commerciales utilisent des compos\u00e9s fluor\u00e9s, avec environ la moiti\u00e9 de la fluorite extraite utilis\u00e9e dans la fabrication de l’acier.\u00a0Le reste de la fluorite est converti en fluorure d’hydrog\u00e8ne corrosif en route vers divers fluorures organiques, ou en cryolite, qui joue un r\u00f4le cl\u00e9 dans le raffinage de l’aluminium.\u00a0La plupart des proc\u00e9d\u00e9s commerciaux d’enrichissement de l’uranium (diffusion gazeuse et m\u00e9thode de centrifugation gazeuse) exigent que l’uranium soit sous forme gazeuse. Par cons\u00e9quent, le concentr\u00e9 d’oxyde d’uranium doit d’abord \u00eatre converti en hexafluorure d’uranium, qui est un gaz \u00e0 des temp\u00e9ratures relativement basses.\u00a0Les mol\u00e9cules contenant une liaison carbone-fluor ont souvent une stabilit\u00e9 chimique et thermique tr\u00e8s \u00e9lev\u00e9e;\u00a0leurs principales utilisations sont les r\u00e9frig\u00e9rants, l’isolation \u00e9lectrique et les ustensiles de cuisine, le dernier \u00e9tant le PTFE (t\u00e9flon).<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\n
\n

Calcium<\/a><\/h3>\n

La plus grande utilisation de calcium m\u00e9tallique est dans la sid\u00e9rurgie, en raison de sa forte affinit\u00e9 chimique pour l’oxyg\u00e8ne et le soufre.\u00a0Ses oxydes et sulfures, une fois form\u00e9s, donnent des inclusions d’aluminate de chaux liquide et de sulfure dans l’acier qui flottent.\u00a0Les compos\u00e9s de calcium sont utilis\u00e9s dans la fabrication d’insecticides, de peintures, de craie \u00e0 tableau noir, de textiles et de feux d’artifice.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
