Lithium et Sodium – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n
\n
\"\"<\/div>
\n

Lithium<\/h3>\n

C’est un m\u00e9tal alcalin doux et blanc argent\u00e9.\u00a0Dans des conditions standard, c’est le m\u00e9tal le plus l\u00e9ger et l’\u00e9l\u00e9ment solide le plus l\u00e9ger.\u00a0Comme tous les m\u00e9taux alcalins, le lithium est hautement r\u00e9actif et inflammable et est stock\u00e9 dans de l’huile min\u00e9rale.

\n

Sodium<\/h3>\n

Le sodium est un m\u00e9tal mou, blanc argent\u00e9 et hautement r\u00e9actif.\u00a0Le sodium est un m\u00e9tal alcalin, appartenant au groupe 1 du tableau p\u00e9riodique, car il poss\u00e8de un seul \u00e9lectron dans sa coque externe qu’il donne facilement, cr\u00e9ant un atome charg\u00e9 positivement, le cation Na+.

Lithium et Sodium – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Lithium<\/a><\/h3>\n

Le lithium a de nombreuses applications, de la graisse lubrifiante, aux ajouts d’alliages notamment pour les alliages d’aluminium et de magn\u00e9sium, aux \u00e9maux pour c\u00e9ramiques, et enfin, les batteries au lithium.\u00a0En particulier, le lithium joue et continuera de jouer un r\u00f4le de plus en plus important dans l’avenir de l’air pur aliment\u00e9 par batterie.\u00a0Les batteries au lithium sont largement utilis\u00e9es dans les appareils \u00e9lectroniques grand public portables et dans les v\u00e9hicules \u00e9lectriques allant des v\u00e9hicules de grande taille aux jouets radiocommand\u00e9s.\u00a0Le terme \u00ab\u00a0batterie au lithium\u00a0\u00bb fait r\u00e9f\u00e9rence \u00e0 une famille de diff\u00e9rentes chimies lithium-m\u00e9tal, comprenant de nombreux types de cathodes et d’\u00e9lectrolytes, mais tous avec du lithium m\u00e9tallique comme anode.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\n
\n
\n

Sodium<\/a><\/h3>\n

Le sodium m\u00e9tallique est principalement utilis\u00e9 pour la production de borohydrure de sodium, d’azoture de sodium, d’indigo et de triph\u00e9nylphosphine.\u00a0Une utilisation autrefois courante \u00e9tait la fabrication de t\u00e9tra\u00e9thylplomb et de titane m\u00e9tallique;\u00a0en raison de l’abandon du TEL et des nouvelles m\u00e9thodes de production de titane.\u00a0Un courant \u00e9lectrique et de la vapeur de sodium se combinent pour former une lueur jaun\u00e2tre.\u00a0Ce principe est utilis\u00e9 pour la fabrication des lampes \u00e0 vapeur de sodium.\u00a0Le sodium est parfois utilis\u00e9 comme agent d’\u00e9change de chaleur dans les centrales nucl\u00e9aires.\u00a0Le sodium liquide est scell\u00e9 dans des tuyaux entourant le c\u0153ur du r\u00e9acteur.\u00a0La chaleur g\u00e9n\u00e9r\u00e9e est absorb\u00e9e par le sodium et forc\u00e9e \u00e0 travers les tuyaux dans un \u00e9changeur de chaleur qui peut \u00eatre utilis\u00e9 pour g\u00e9n\u00e9rer de l’\u00e9lectricit\u00e9.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
