QUE SIGNIFIE 비스무트 EN CORÉEN
Bismuth
Le bismuth est un élément chimique avec le symbole Bi, numéro atomique 83, poids atomique 208.980. Le point de fusion est de 271,3 ° C et le point d'ébullition est de 1560 ° C. La densité est de 9,747 g / cm3\u003e à la température ambiante. Il est aussi appelé kanji comme kanji. Il est lourd et fragile, il a une teinte blanche de métal et a une similarité chimique avec l'arsenic et l'antimoine. Semi-magnétique est le plus fort parmi les métaux. Le mercure est le prochain plus bas en termes de conductivité thermique. Les composés de bismuth sans plomb sont utilisés dans les cosmétiques et les traitements médicaux. Tous les isotopes sont radioactifs, mais leur demi-vie est très longue et peut être classée comme stable. Il est obtenu à partir de minerais tels que les métaux purs, les bordures de fenêtre, et la pierre de bordure, et est le plus commun en Bolivie. Plomb, cuivre, étain, argent et or.
