Kugwiritsa ntchitoniobiumMonga chowonjezera cha iron-based, nickel-based superalloys ndi zirconium, niobium imatha kupititsa patsogolo mphamvu zawo. M'makampani opanga mphamvu za atomiki, niobium ndiyoyenera kugwiritsidwa ntchito ngati zida zomangira za riyakitala ndi zida zomangira zamafuta a nyukiliya, komanso chitetezo chamatenthedwe ndi zida zamapangidwe m'mafakitale oyendetsa ndege ndi zakuthambo. Niobium capacitance ndi yofanana ndi tantalum capacitance, koma chifukwa cha kachulukidwe kakang'ono ka niobium, capacitance pa voliyumu ya unit ndi yayikulu. Niobium titaniyamu, niobium zirconium aloyi, niobium malata, niobium zotayidwa germanium ndi zinthu zina pawiri superconductive si ntchito kufala mphamvu, kupanga mphamvu, kupanga maginito superconducting, ndi kulamulira maphatikizidwe nyukiliya, komanso ntchito pazida navigation mu spacecraft, electromagnetic. zida zothamangitsira zotengera zothamanga kwambiri, ndi superconducting superclass yothamanga kwambiri sitima. Kukana kwa kutu kwa asidi kwa niobium ndikwabwino kuposa zirconium, koma osati kwabwino ngati kwa tantalum. Itha kugwiritsidwa ntchito ngati kutentha exchanger, condenser, fyuluta, agitator, etc. Niobium carbide angagwiritsidwe ntchito paokha kapena osakaniza tungsten carbide ndi molybdenum carbide monga otentha forging akufa, zida kudula, jet injini turbine masamba, mavavu, masiketi mchira ndi rocket. zokutira nozzle. Chitsulo chokhala ndi niobium chili ndi mphamvu zambiri, kulimba bwino komanso kukana kuzimitsa kuzizira, ndipo chimagwiritsidwa ntchito kwambiri pamapaipi amafuta. Lithium niobate single crystal imagwiritsidwa ntchito pamitundu yama TV. Chikhalidwe cha niobium niobium ndi chitsulo chosowa chosowa chokhala ndi chitsulo chotuwa chotuwa, ndipo malo ake osungunuka ndi 2467. C. Kuchuluka kwake ndi 8.6 g/cm3. Niobium ili ndi pulasitiki yabwino yotsika kutentha ndipo imatha kusinthidwa kukhala zinthu zosiyanasiyana zomaliza ndi kuzizira. Kukana kutentha kwapamwamba, mphamvu zambiri, pa 1000. C ndi pamwamba akadali ndi mphamvu zokwanira, pulasitiki ndi matenthedwe matenthedwe. Superconductivity ndi yabwino kwambiri pa kutentha kochepa kwambiri, monga minus 260. Kukaniza kuli pafupi ndi zero pafupifupi C. Pa 150. Pansi pa C, kumagwirizana ndi kuwonongeka kwa mankhwala ndi mlengalenga. Ndi wokhazikika kwa ambiri asidi ndi mchere njira kutentha firiji, koma sungunuka wa haidrojeni embrittlement. Filimu yokhazikika ya oxide imapangidwa panthawi ya anodization. Mu mchere wachilengedwe, niobium. Filimu yokhazikika ya oxide imapangidwa panthawi ya anodization. Mu mchere wachilengedwe, niobium ndi tantalum zimakhala. Mchere wokhala ndi niobium ndi tantalum umaphatikizapo pyrochlore, niobium-tantalite, limonite, niobium-titanium-bearing rutile, rutile ndi niobium-tantalate placer. Ma slag ena opangira zitsulo ndi malata osungunula ndi zinthu zofunika kwambiri pakuyenga niobium. Magulu a niobium ore kapena tantalum ore amatsimikiziridwa ndi kuchuluka kwa niobium kapena tantalum mu mchere. The Nb-Tn superconducting maginito katundu wafika pamlingo wapadziko lonse lapansi. Baoji Research Institute of Rare Nonferrous Metal Processing yapanga moyeserera maginito a Multicore Nb-Tn superconducting maginito okhala ndi mainchesi 23.5 mm pogwiritsa ntchito waya wake. Poyerekeza ndi maginito ochiritsira, maginito amtunduwu ali ndi voliyumu yaying'ono, kulemera kwake komanso mphamvu yayikulu yamagetsi; Pambuyo pamagetsi ndi ntchito yotsekedwa, magetsi safunikira kuti azigwira ntchito nthawi yayitali. Malinga ndi mayeso opangidwa ndi Chinese ndi French ogwira ntchito sayansi ndi luso mu labotale mkulu-munda wa National Research Center of France, pa - 286.96 ℃, chapakati munda mphamvu ya maginito kufika 154000 Gauss, ndi ntchito yake ukufika mlingo mayiko. .
