Zirconium alloy yog non-ferrous alloy tsim los ntawm kev ntxiv lwm cov ntsiab lus rau zirconium raws li matrix. Lub ntsiab alloying ntsiab yog tin, niobium, hlau, thiab lwm yam. Zirconium alloy muaj zoo corrosion kuj, nruab nrab txhua yam khoom, tsis tshua muaj atomic thermal neutron absorption cross section, zoo compatibility nrog nuclear roj, thiab feem ntau yog siv raws li ib tug core structural khoom rau dej- txias nuclear reactors nyob rau hauv qhov kub thiab txias dej siab thiab chav ntawm 300 ~ 400 degree. Tsis tas li ntawd, zirconium muaj kev tiv thaiv zoo heev rau ntau yam acids, alkalis thiab ntsev, thiab muaj kev sib raug zoo rau cov pa oxygen, nitrogen thiab lwm yam gases, yog li zirconium alloys kuj tseem siv rau hauv kev tsim cov khoom tiv thaiv corrosion thiab cov khoom siv tshuaj, thiab tau dav siv los ua cov uas tsis yog-evapotranspiration degassing cov neeg ua haujlwm hauv lub tshuab nqus tsev hluav taws xob thiab lub teeb pom kev lag luam.
Muaj ob hom zirconium alloys ua rau ntawm kev lag luam: zirconium-tin thiab zirconium-niobium. Cov qib alloy ntawm yav dhau los yog Zr-2 thiab Zr-4, thiab tus neeg sawv cev ntawm yav dhau los yog Zr-2.5Nb. Nyob rau hauv zirconium-tin alloys, cov alloying ntsiab tin, hlau, chromium, thiab npib tsib xee tuaj yeem txhim kho lub zog, corrosion resistance, thiab thermal conductivity ntawm corrosion-resistant zaj duab xis, thiab txo qhov rhiab heev ntawm lub xeev ntawm corrosion. Feem ntau Zr-2 alloy yog siv rau hauv boiling dej reactors, thiab cov Zr-4 alloy yog siv nyob rau hauv pressurized dej reactors. Nyob rau hauv zirconium-niobium alloys, qhov corrosion kuj ntawm cov hlau yog qhov zoo tshaj plaws thaum tus nqi ntawm niobium ntxiv kom ncav cuag qhov kev txwv ntawm cov qauv siv lead ua ntawm zirconium ntawm qhov kev pabcuam kub. Zirconium alloy muaj homogeneous heterocrystalline transformation, thiab cov qauv siv lead ua yog lub cev-centered cubic ntawm qhov kub thiab txias-packed hexagonal ntawm qis kub. Zirconium alloys muaj cov yas zoo thiab tuaj yeem ua rau hauv cov kav dej, phaj, tuav thiab xaim los ntawm kev ua cov yas, thiab lawv cov weldability kuj zoo, uas tuaj yeem siv rau kev ua vuam.
Zirconium muaj ib qho me me thermal neutron capture cross-section thiab zoo heev nuclear zog, uas yog ib tug indispensable khoom rau txoj kev loj hlob ntawm lub atomic zog kev lag luam thiab yuav siv tau raws li ib tug structural khoom rau reactor cores. Zirconium hmoov yog flammable nyob rau hauv cov huab cua thiab yuav siv tau raws li ib tug detonator thiab smokeless gunpowder. Zirconium tuaj yeem siv los ua cov khoom siv ntxiv rau deoxidation thiab desulfurization ntawm cov hlau zoo, thiab tseem yog ib feem ntawm cov hlau armor, cannon steel, stainless hlau thiab kub-resistant steel. Zirconium yog ib qho tseem ceeb ntawm cov hlau alloying hauv magnesium alloys, uas tuaj yeem txhim kho lub zog tensile thiab kev ua haujlwm ntawm magnesium alloys. Zirconium kuj yog tus neeg sawv cev metamorphic rau aluminium-magnesium alloys, uas tuaj yeem ua kom zoo dua cov nplej. Zirconia thiab zircon yog cov khoom tseem ceeb tshaj plaws hauv refractories. Zirconia yog cov khoom tseem ceeb ntawm cov ceramics tshiab thiab tsis tuaj yeem siv los ua cov khoom siv cua sov kom tiv taus qhov kub thiab txias oxidation. Zirconia tuaj yeem siv los ua ib qho ntxiv rau cov kua qaub-resistant enamel thiab iav, uas tuaj yeem txhim kho elasticity, tshuaj stability thiab kub ua hauj ntawm iav. Zircon muaj zog lub teeb pom kev ua tau zoo thiab zoo thermal stability, thiab tuaj yeem siv los ua tshuaj pleev thaiv hnub hauv ceramics thiab iav. Zirconium tuaj yeem nqus tau ntau cov pa oxygen, hydrogen, ammonia thiab lwm cov pa roj thaum cua sov, thiab yog tus neeg sawv cev zoo tshaj plaws, xws li zirconium hmoov ua tus neeg sawv cev degassing hauv cov hlab hluav taws xob, thiab zirconium hlau zirconium nplooj ntawv raws li qhov rooj txhawb nqa, kev txhawb nqa anode, thiab lwm yam. .
