Khoom Taw qhia
Niobium bar yog tsim los ntawm niobium ingot. Ua ntej, dov lub niobium ingot mus rau txoj cai loj loj niobium pas nrig, acid pickling nto ntawm niobium pas nrig kom tshem tawm cov roj thiab impurities, thiab ces ntxuav nrog dej ntshiab, luas ob kawg ntawm niobium pas nrig, ces ntxuav dua. Thaum kawg, raws li qhov xav tau tiag tiag, txiav thiab ncab rau ntau zaus, kom txog rau thaum tau txais qhov loj ntawm niobium pas nrig.
Niobium yog ib hom xim hlau grey lustrous tsawg refractory hlau, lub melting point ntawm 2467 degree, qhov ceev yog 8.6g / cm3. Niobium muaj qhov zoo ntawm qhov kub thiab txias, tuaj yeem ua kom txias-siab ua ntau hom, phaj, hlau qws khoom. Lub zog siab Nb, muaj peev xwm, ntau tshaj 1000 degree tseem muaj zog txaus, plasticity thiab thermal conductivity. Superconductivity yog qhov zoo tshaj plaws ntawm qhov kub thiab txias, xws li hauv qhov rho tawm 260 degrees Celsius thiab qhov tsis kam yog ze rau xoom, tam sim no yog cov khoom tseem ceeb tshaj plaws superconducting.
Niobium bar thiab cov khoom siv hlau muaj qhov siab melting point, corrosion resistant, txias ua kev ua tau zoo thiab lwm yam ntxwv, lug siv nyob rau hauv tshuaj, electronics, aviation thiab aerospace thiab lwm yam kev lag luam. Niobium thiab niobium alloy rods yog siv los ua cov khoom siv thiab txhua yam ntawm aviation cav niobium alloy foob pob ua ntxaij nozzle (niobium alloy nozzle), lub reactor sab hauv cov khoom thiab cov ntaub ntawv pob, zus tau tej cov nitric acid, hydrochloric acid los yog sulfuric acid corrosion kuj nyob rau hauv cov xwm txheej ntawm corrosion-resistant qhov chaw. Koom nrog hauv niobium zirconium tuaj yeem txhim kho oxidation tsis kam thiab lub zog ntawm cov ntaub ntawv, niobium thiab niobium zirconium alloy hlau tau dav siv hauv kev tsim cov hluav taws xob siab sodium teeb thiab electrolytic capacitor anode.
Specification:
1.Diameter: 0.5 mm ~ 100 mm.
2.Length: mus txog 2 meters, tej zaum yuav muaj nyob rau hauv tshwj xeeb daim ntaub ntawv.
3.Purity: qib lag luam (99.9% purity) ~ ultra-siab purity (99.999% purity).
4.Nto tiav: polished, kos, thiab hauv av.
5.Tolerance: nyob ntawm txoj kab uas hla thiab ntev, tab sis feem ntau yog nyob ntawm ±0 01 hli mus rau ± 0.5 hli.
6.Alloying cov ntsiab lus: Niobium rods tuaj yeem ua alloyed nrog lwm cov hlau, xws li titanium, zirconium, thiab tungsten, los txhim kho lawv cov khoom rau kev siv tshwj xeeb.
