Cov khoom ntawm Bismuth Alloys
Jan 15, 2022
Bismuth alloys muaj cov cuab yeej ntawm tsis shrinking thaum solidified, thiab yog siv rau casting thiab luam ntawv hom thiab high-precision pwm.
Bismuth alloys feem ntau yog siv los ua cov khoom ntxiv hauv cov hlau cam, steel thiab aluminium alloys los txhim kho kev ua haujlwm ntawm cov hlau. Ib qho bismuth alloy uas muaj 11% antimony yog siv los ua infrared detectors. Bismuth-tin thiab bismuth-cadmium alloys yog siv los ua auxiliary electrodes rau selenium rectifiers.
A magnetometer was fabricated by utilizing the characteristic of bismuth's sharp decrease in resistivity under the action of a magnetic field. Bismuth-manganese alloys can be used as permanent magnet materials. Bismuth has a small thermal neutron absorption cross section, low melting point and high boiling point, and can be used as a heat transfer medium in nuclear reactors.
Bismuth telluride tau siv dav los ua cov khoom siv hluav taws xob rau lub hnub ci, thiab bismuth telluride tuaj yeem txhim kho kev ceev thiab kev ua haujlwm ntawm lub computer chips.
Bismuth-silver-cesium alloy tuaj yeem siv los tsim cov tshuab hluav taws xob photoelectric, nyiaj-bismuth sulfide yog siv los tsim cov twj paj nruag semiconductor, thiab bismuth-cadmium thermoelectric cov ntsiab lus yog siv rau lub tswb nrov.
