Bismuth

Bismuth yog qhia nyob rau hauv lub sij hawm nrog lub cim Bi, atomic tooj 83, thiab atomic mass ntawm 208.98. Bismuth yog nkig, crystalline, dawb hlau nrog me ntsis liab tinge. Nws muaj ntau yam kev siv, suav nrog tshuaj pleev ib ce, alloys, tua hluav taws thiab mos txwv. Nws yog qhov zoo tshaj plaws paub tias yog cov khoom tseem ceeb hauv kev kho mob plab xws li Pepto-Bismol.

Bismuth, lub ntsiab lus 83 ntawm lub sij hawm lub sij hawm ntawm lub ntsiab lus, yog ib qho kev hloov pauv tom qab hlau, raws li Los Alamos National Laboratory. (Txoj kev sib txawv ntawm lub rooj zaum sawv cev rau nws raws li kev hloov pauv hlau.) Cov hlau hloov pauv - pawg loj tshaj plaws ntawm cov ntsiab lus, uas suav nrog tooj liab, txhuas, hlau, zinc thiab kub - nyuaj heev, nrog cov ntsiab lus melting siab thiab cov ntsiab lus kub. Tom qab kev hloov pauv hlau qhia qee yam ntawm cov hlau hloov pauv tab sis yog softer thiab ua tsis zoo. Qhov tseeb, bismuth's hluav taws xob thiab thermal conductivity yog qhov txawv txav rau cov hlau. Nws kuj muaj qhov tshwj xeeb uas tsis tshua muaj melting point, uas ua rau nws tsim cov alloys uas tuaj yeem siv rau pwm, ntsuas hluav taws thiab tua hluav taws.

Bismuth hlau yog siv nyob rau hauv kev tsim cov khoom uas tsis tshua muaj melting solders thiab fusible alloys nrog rau tsawg toxicity noog tua thiab nuv ntses sinkers. Qee cov bismuth tebchaw kuj tau tsim thiab siv los ua tshuaj. Kev lag luam ua rau siv cov bismuth tebchaw ua catalysts hauv manufacturing acrylonitrile, cov khoom pib rau hluavtaws fibers thiab roj hmab. Bismuth yog qee zaum siv rau hauv kev tsim cov tshuaj tua kab thiab cov phom tua.

Cov Khoom Siv Tshwj Xeeb nplua nuj yog ib lub chaw tsim khoom ntawm Sputtering Target thiab tuaj yeem tsim cov khoom siv siab huv Bismuth Sputtering raws li cov neeg siv khoom tshwj xeeb. Yog xav paub ntxiv, thov hu rau peb.
