Kev sivniobiumUa ib qho kev ntxiv rau cov hlau-raws li, npib tsib xee thiab zirconium-raws supallloys, Niobium tuaj yeem txhim kho lawv cov khoom muaj zog. Nyob rau hauv lub atomic zog kev lag luam, Niobium yog tsim nyog siv los ua cov khoom siv hluav taws xob, nrog rau cov khoom siv thermal thiab cov qauv qauv hauv kev lag luam thiab aerospace kev lag luam. Niobium Capacitance zoo ib yam li Tantalum capacitance, tab sis vim muaj qhov me me ntawm niobium, lub peev xwm ib txwm ntim yog qhov loj dua. Niobium titanium, niobium zirconium alloy, niobium alloy germanium thiab kuj tseem siv rau cov khoom siv tsheb loj tsheb ciav hlau siab. Cov acid corrosion tsis kam ntawm niobium zoo dua li ntawm zirconium, tab sis tsis zoo li ntawm tantalum. Nws tuaj yeem siv los ua cua sov ua kom zoo nkauj, lim, agitator, thiab lwm yam, tus Tsovail tiab thiab foob pob hluav taws xob ua ke. Niobium-muaj alloy steel muaj lub zog siab, kev ua kom muaj zog thiab txias quenching Kuj, thiab yog siv dav hauv cov roj pipelines. Lithium niobate tib lub sivchstal yog siv rau hauv TV TV teeb. Qhov xwm ntawm niobium niobium yog ib tug refactory tsawg hlau nrog hlau grey luster, thiab nws lub ntsiab lus meter yog 2467. C. Lub ntom ntom yog 8.6 g / cm3. Niobium muaj cov khoom siv tsawg-kub thiab tuaj yeem ua tiav rau ntau yam khoom tiav los ntawm kev txias. Cov kub ua hauj kub ua kom tau, muaj zog siab, ntawm 1000. C thiab siab dua muaj lub zog txaus, cov yas thiab thermal conductivity. Superconductivity yog qhov zoo tshaj plaws ntawm tsawg heev, xws li rho tawm tsawg dua ntawm C. ntawm C. hauv 150. Hauv qab ntawm 150. Hauv qab ntawm 150. Nws yog ruaj khov rau ntau cov kua qaub thiab ntsev cov kev daws teeb meem ntawm chav tsev kub, tab sis soluble hauv hydrogen embrittlement. Zaj duab xis ruaj khov khov kho yog tsim thaum lub sij hawm anodization. Nyob rau hauv cov zaub mov muaj ntuj, niobium. Zaj duab xis ruaj khov khov kho yog tsim thaum lub sij hawm anodization. Nyob rau hauv cov zaub mov tej zaub mov, niobium thiab tantalum coos. Cov zaub mov muaj cov zaub mov muaj niobium thiab tantalum suav nrog pyrochlore, niobium-tantile, Niobium-titile, rutile-tantalate placer. Ib co steelmaking slag thiab tin smelting slag kuj tseem tseem ceeb cov peev txheej rau refining niobium. Kev faib tawm Niobium ore lossis tantalum gore yog feem ntau txiav txim siab los ntawm tus nqi ntawm niobium lossis tantalum hauv cov ntxhia. NB-tn superconducting cov khoom sib nqus tau mus txog cov theem hauv ntiaj teb. Baeji Lub Tsev Haujlwm Tshawb Fawb ntawm tsis tshua muaj kev sim ua haujlwm tau ua tiav txoj kev sim ua ke-tn superconducting cov hlau nplaum ntawm 23.5 hli siv nws tus kheej hlau. Piv nrog cov hlau nplaum, cov hlau nplaum no muaj cov ntim me me, lub teeb hnyav thiab muaj zog sib nqus lub zog; Tom qab lub zog-rau thiab kaw ua haujlwm, muab fais fab tsis tas yuav tsum muaj rau kev ua haujlwm ntev. Raws li kev xeem ua los ntawm Suav thiab cov neeg ua haujlwm ntawm cov neeg ua haujlwm hauv tebchaws
