Bismuth hlau

Cov lus piav qhia luv luv:

Bismuth yog lub ntsej muag hlau nrog cov xim liab dawb, xim liab thiab nws ruaj khov nyob rau hauv ob qho tib si qhuav thiab noo cua ntawm qhov kub thiab txias. Bismuth muaj ntau cov kev siv uas coj kom zoo dua ntawm nws cov khoom tshwj xeeb xws li nws tsis muaj tshuaj lom, tsis tshua muaj zog, thiab cov tsos mob.

Bismuth yog silvery dawb rau cov hlau liab, uas feem ntau yog siv los npaj cov ntaub ntawv soob, cov tub rog thiab cov roj ua kua rau hauv nuclele reactors, ect. Bismuth tshwm sim nyob rau hauv cov li cov hlau dawb thiab ntxhia.

Yam zoo

1.High-purity bismuth feem ntau yog siv nyob rau hauv kev lag luam nuclear, aerospace kev lag luam, hluav taws xob kev lag luam thiab lwm yam haujlwm.

2.Ssis Bismuth muaj semiconding cov yam ntxwv, nws kev tiv thaiv tsawg dua nrog kev nce kub ntawm tsawg kub. Hauv thermocooling thiab thermoelectric lub zog tiam, bi2te3 thiab bi2se3 alloys thiab bi-sb-tb-te ternary alloys nyiam ntau tshaj plaws. Nyob rau hauv-bi alloy thiab PB-bi alloy yog superconducting cov ntaub ntawv.

3.bismuth tsis tshua pom kev, siab ntom ntom, lub vapor siab tsawg, thiab me me neutron kev ua kom haum seem, uas tuaj yeem siv rau hauv siab-kub attractors.

Daim ntawv thov

1. Nws tsuas yog siv los npaj cov khoom sib xyaw semiconductor, thermoelectric tub yees, cov tub rog thiab cov zaub mov kom txias nyob rau hauv nuclear reactors.

2.Us rau npaj semiconductor siab-huv cov ntaub ntawv thiab kev loj-purity bismut rau. Siv raws li txias rau hauv atomic reactors.

3. Nws tsuas yog siv hauv cov tshuaj, fuse melting point alloy, fuse, iav thiab ceramics, thiab kuj yog ib qho catalyst rau cov roj hmab ntau lawm.
