Kawm txog kev bismuth

Bismuth yog silvery dawb rau cov hlau liab uas yog nkig thiab zom zaws. Nws cov tshuaj lom neeg muaj qhov ruaj khov. Bismuth muaj nyob rau hauv cov xwm nyob rau hauv daim ntawv ntawm cov hlau dawb thiab cov zaub mov.

Bismuth yog cov hlau muag muag, thaum tsis txhob lam tau bismuth yog nkig. Nws yog ruaj khov nyob rau hauv chav tsev kub. Nws lub ntsiab lus tseem ceeb yog Bismuthinite (Bi2s5) thiab Bismuth Ocher (Bi2o5). Ua kua Bismuth nthuav thaum solorified.
Nws yog nkig thiab muaj hluav taws xob tsis zoo thiab thermal conductivity. Bismuth Selenide thiab Inderuride muaj cov khoom ntiag tug semiconductor.
Bismuth hlau yog ib qho silvery dawb (paj yeeb) mus rau lub teeb daj Nyob rau hauv chav tsev kub, bismuth tsis hnov ​​mob nrog oxygen lossis dej thiab nyob ruaj khov hauv huab cua. Nws muaj cov hluav taws xob tsis zoo thiab thermal ua haujlwm; Bismuth tau pom yav dhau los yog qhov ruaj khov tshaj plaws nrog cov kev sib txheeb zoo tshaj plaws atomic loj thiab xyoo 2003, tau raug lwj ua rau kev noj qab haus huv-205 los ntawm α. Nws ib nrab-lub neej yog txog 1.9x10 ^ 19 xyoo, uas yog 1 txhiab zaug lub neej ntawm lub ntiaj teb.
2. Daim Ntawv Thov
Semiconductor
Cheebtsam semiconductor ua los ntawm kev sib txuas ua ke siab-purity bismuth nrog seepocus, tsawg-kub thermoelectric fais tiam thiab thermorefigeration. Lawv tau siv los sib dhos ua cua txias thiab tub yees. Khoom siv Bismuth sulfide tuaj yeem siv los tsim cov kws ntaus ntawv hauv cov khoom siv photo-ensitivity los nce cov rhiab hauv cheeb tsam pom.
Kev Lag Luam Nuclear
Cov khoom noj muaj zog pismuth yog siv los ua cov cab hlau kub lossis txias hauv Nuclear kev lag luam reactors thiab raws li cov khoom siv rau kev tiv thaiv atomic fission.
Hauv Ceramics
Kev ua bismuth-muaj nyob rau hauv cov lus hauv hluav taws xob xws li cov khoom siv tshuab hluav taws xob tsis zoo, cov duab hluav taws xob yog cov khoom siv hluav taws xob nucigry, entro-optics, piezoelectric lasers thiab lwm yam khoom siv; Bismuth Calcadium (Pomegranate ferrite yog cov hlau nplaum thiab hmoov av Ntau tshaj 10 lwm cov ntaub ntawv kuj tau pib siv hauv kev lag luam.
Kev Kho Mob
Cov tebchaw muaj qhov cuam tshuam los ntawm cov qub txeeg qub teg, tshuaj tiv thaiv kab mob, thiab kho mob plab zom mov dyspepsia. Bismuth subcarbonate, bismuth subnitrate, thiab poov tshuaj bismuth bismuth subrubberate yog siv los ua plab. Cov nyhuv astringent ntawm cov tshuaj bismuth tau siv rau kev phais mob los kho kev ua kom ntshav thiab tsis txhob los ntshav. Nyob rau hauv radiotherapy, cov alloys raws li ntawm txhuas kom tiv thaiv cov phiaj rau cov neeg mob los tiv thaiv lwm qhov ntawm lub cev los ntawm kev raug hluav taws xob. Nrog rau kev txhim kho cov tshuaj siv cov tshuaj bismuth, nws tau pom tias qee cov tshuaj bismuth muaj cov kev cuam tshuam cancer cancer.
Txuas ntxiv metallurgical
Ntxiv cov nqi khi ntawm kev bismuth rau cov hlau tuaj yeem txhim kho kev ua cov khoom siv ntawm cov hlau, thiab ntxiv cov kab nrib nrob hlau tuaj yeem ua kom nws muaj cov khoom sib thooj rau cov hlau uas stainless.
