Kodi Bismuth CAS 7440-69-9 ndi chiyani?

Bismuth imatha kuyatsa yokha mu gasi wa chlorine ndikuphatikizana mwachindunji ndi bromine, ayodini, sulfure, ndi selenium kupanga ma trivalent compounds ikatenthedwa. Insoluble mu kuchepetsa hydrochloric acid ndi kuchepetsa sulfuric acid, sungunuka mu asidi nitric ndi anaika sulfuric asidi kupanga trivalent bismuth mchere. Mchere waukulu umaphatikizapo bismuthinite ndi bismuthinite. Kuchuluka mu kutumphuka kwa dziko lapansi ndi 2.0 × 10-5%.

Kugwiritsa ntchito

Kugwiritsiridwa ntchito kwakukulu kwa bismuth kumakhala ngati chigawo chochepa chosungunuka (kusungunuka) ma alloys a zipangizo zotetezera moto, kukhudzana ndi zitsulo, ndi matenthedwe opangira magetsi. Amagwiritsidwa ntchito pokonzekera mankhwala ochizira matenda a m'mimba ndi chindoko. Amagwiritsidwa ntchito pazida zamagetsi (ma aloyi a thermoelectric ndi maginito okhazikika). Ntchito monga chothandizira, makamaka yokonza acrylonitrile. Kutentha kwakukulu kwa ceramics ndi pigments, etc.
