Chii chinonzi Bismuth CAS 7440-69-9?

Bismuth inogona kuzvibatidza yega mugesi yeklorini uye yakanangana nebromine, iodine, sarufa, uye selenium kugadzira makomisheni matatu kana yapiswa. Insoluble mu dilute hydrochloric acid uye inonyungudutsa sulfuric acid, inonyungudika munitric acid uye yakanyungudutswa sulfuric acid kugadzira trivalent bismuth munyu. Maminerari makuru anosanganisira bismuthinite uye bismuthinite. Kuwanda kuri muPasi pevhu ndiko 2.0 × 10-5%.

Application

Iko kushandiswa kukuru kwebismuth kwakafanana nechikamu chekuderera kunyunguduka (kunyunguduka) alloys yemidziyo yekudzivirira moto, masimbi anobatika, uye thermal conductive media. Inoshandiswa kugadzirira mishonga yekurapa zvirwere zvemudumbu uye syphilis. Inoshandiswa kumidziyo yemagetsi (thermoelectric alloys uye magineti asingagumi). Inoshandiswa sechinhu chinokonzera, kunyanya mukugadzirira kweacrylonitrile. Yakakwira tembiricha ceramics uye pigment, nezvimwe.
