Iyini i-Bismuth CAS 7440-69-9?

I-Bismuth ingazithungela yona ngokwayo ngegesi ye-chlorine futhi ihlangane ngokuqondile ne-bromine, i-iodine, isulfure, ne-selenium ukuze yakhe izinhlanganisela ezincanyana lapho ishiswa. Ayincibiliki ku-dilute hydrochloric acid futhi ihlanza i-sulfuric acid, inyibilika ku-nitric acid kanye ne-sulfuric acid egxilile ukuze yakhe usawoti we-bismuth we-trivalent. Amaminerali amakhulu afaka i-bismuthinite ne-bismuthinite. Ubuningi kuqweqwe lomhlaba ngu-2.0 × 10-5%.

Isicelo

Ukusetshenziswa okuyinhloko kwe-bismuth kuyingxenye yokuncibilika okuphansi (okuncibilika) ama-alloys emishini yokuvikela umlilo, othintana nabo bensimbi, kanye nemidiya ye-thermal conductive. Isetshenziselwa ukulungisa imithi yokwelapha izifo zesisu kanye ne-syphilis. Isetshenziselwa izinto zikagesi (ama-alloys e-thermoelectric kanye nozibuthe ongapheli). Isetshenziswa njenge-catalyst, ikakhulukazi ekulungiseleleni i-acrylonitrile. Izinga lokushisa eliphakeme le-ceramics nezingulube, njll.
