Yintoni i-Bismuth CAS 7440-69-9?

I-Bismuth inokuzitshisa kwigesi yeklorini kwaye idibanise ngokuthe ngqo ne-bromine, iodine, isulfure, kunye ne-selenium ukwenza iikhompawundi ze-trivalent xa ishushu. Ayinyibiliki kwi-dilute hydrochloric acid kunye ne-asidi ye-sulfuric, enyibilikayo kwi-nitric acid kunye ne-asidi yesulfuric egxininisiweyo ukwenza iityuwa ze-bismuth ezintathu. Iiminerali eziphambili ziquka i-bismuthinite kunye ne-bismuthinite. Ubuninzi kwi-crust yomhlaba yi-2.0 × 10-5%.

Isicelo

Ukusetyenziswa okuphambili kwe-bismuth njengenxalenye ye-alloys encibilikayo ephantsi (i-melting) yezixhobo zokukhusela umlilo, uqhagamshelwano lwetsimbi, kunye nemidiya ye-thermal conductive. Isetyenziselwa ukulungiselela amayeza okunyanga izifo zesisu kunye ne-syphilis. Isetyenziselwa izixhobo zombane (ii-alloys ze-thermoelectric kunye neemagnethi ezisisigxina). Isetyenziswe njenge-catalyst, ngakumbi ekulungiseleleni i-acrylonitrile. I-ceramics yobushushu obuphezulu kunye ne-pigments, njl.
