Bismuth CAS 7440-69-9 yog dab tsi?

Bismuth tuaj yeem ua rau nws tus kheej ignite hauv cov roj chlorine thiab ncaj qha ua ke nrog bromine, iodine, sulfur, thiab selenium los ua cov sib xyaw ua ke thaum rhuab. Insoluble nyob rau hauv dilute hydrochloric acid thiab dilute sulfuric acid, soluble nyob rau hauv nitric acid thiab concentrated sulfuric acid los ua trivalent bismuth ntsev. Cov zaub mov tseem ceeb suav nrog bismuthinite thiab bismuthinite. Qhov kev nplua nuj nyob hauv lub ntiaj teb daim tawv nqaij yog 2.0 × 10-5%.

Daim ntawv thov

Kev siv lub ntsiab ntawm bismuth yog ib feem ntawm cov melting uas tsis tshua muaj melting (melting) alloys rau cov khoom siv tiv thaiv hluav taws, tiv thaiv hlau, thiab thermal conductive media. Siv los npaj cov tshuaj kho mob plab thiab mob syphilis. Siv rau cov khoom siv hluav taws xob (thermoelectric alloys thiab cov hlau nplaum ruaj khov). Siv raws li ib tug catalyst, tshwj xeeb tshaj yog nyob rau hauv kev npaj ntawm acrylonitrile. Kub kub ceramics thiab pigments, thiab lwm yam.
