Ukusetyenziswa kweniobiumNjengesongezo se-iron-based, i-nickel-based and zirconium-based superalloys, i-niobium inokuphucula iimpawu zabo zamandla.Kushishino lwamandla e-atom, i-niobium ifanelekile ukusetyenziswa njengemathiriyeli yesakhiwo sereactor kunye nemathiriyeli yokugquma yesibaso senyukliya, kunye nokhuseleko lobushushu kunye nemathiriyeli yesakhiwo kushishino lwezomoya kunye ne-aerospace.I-Niobium capacitance ifana ne-tantalum capacitance, kodwa ngenxa yoxinano oluncinci lwe-niobium, i-capacitance ngeyunithi yeyunithi inkulu.I-niobium titanium, i-niobium zirconium alloy, i-niobium tin, i-niobium aluminiyam igermanium kunye nezinye izinto ezixubeneyo ze-superconductive azisetyenziselwa ukuhambisa amandla, ukuveliswa kwamandla, ukuveliswa kweemagnethi ezinkulu, kunye nokulawulwa kwe-nyukliya fusion, kodwa ikwasetyenziselwa izixhobo zokuhamba kwi-spacecraft, i-electromagnetic. izixhobo zokuqhubela phambili kwiinqanawa zokuntywila ezinesantya esiphezulu, kunye noololiwe abahamba ngesantya esiphezulu.Ukumelana ne-asidi ye-corrosion ye-niobium ingcono kune-zirconium, kodwa ayilungile njengaleyo ye-tantalum.Ingasetyenziselwa ukutshintshiselana kobushushu, i-condenser, i-filter, i-agitator, njl njl. I-Niobium carbide ingasetyenziswa yodwa okanye idityaniswe ne-tungsten carbide kunye ne-molybdenum carbide njengoko i-forging eshushu iyafa, izixhobo zokusika, ii-injini ze-injini ye-jet, i-valve, iziketi zomsila kunye ne-rocket. iingubo zomlomo.Intsimbi ye-alloy ene-niobium inamandla aphezulu, ukuqina okulungileyo kunye nokumelana nokucima okubandayo, kwaye isetyenziswa ngokubanzi kwimibhobho yeoli.Ikristale yeLithium niobate enye isetyenziswa kwiiseti zikamabonakude ezinemibala.Ubume be-niobium niobium yintsimbi enqabileyo enqabileyo ene-steel grey luster, kunye ne-melting point yi-2467. C. Ubuninzi be-8.6 g / cm3.I-Niobium ineplastiki elungileyo yobushushu obuphantsi kwaye inokulungiswa kwiimveliso ezahlukeneyo ezigqityiweyo ngoxinzelelo olubandayo.Ukumelana nokushisa okuphezulu, amandla aphezulu, kwi-1000. C nangaphezulu kusenamandla okwaneleyo, iplastiki kunye ne-thermal conductivity.I-Superconductivity ingcono kakhulu kumaqondo okushisa aphantsi kakhulu, afana ne-minus 260. Ukuxhatshazwa kusondele kwi-zero malunga ne-C. Kwi-150. Ngezantsi kwe-C, ixhathisa ukubola kweekhemikhali kunye ne-atmospheric corrosion.Izinzile kwizisombululo ezininzi ze-asidi kunye netyuwa kwindawo yobushushu begumbi, kodwa i-soluble kwi-hydrogen embrittlement.Ifilimu ye-oxide ezinzileyo yenziwa ngexesha le-anodization.Kwiiminerali zendalo, i-niobium.Ifilimu ye-oxide ezinzileyo yenziwa ngexesha le-anodization.Kwiiminerali zendalo, i-niobium kunye ne-tantalum zihlala.Izimbiwa ezine-niobium kunye ne-tantalum ziquka i-pyrochlore, i-niobium-tantalite, i-limonite, i-niobium-titanium-bearing rutile, i-rutile kunye ne-niobium-tantalate placer.Enye i-steelmaking slag kunye ne-tin smelting slag nazo zizixhobo ezibalulekileyo zokusulungekisa i-niobium.Ulwahlulo lwe-niobium ore okanye i-tantalum ore luchongwa ikakhulu sisixa se-niobium okanye i-tantalum kwiminerali.Iipropati ze-Nb-Tn superconducting magnetic ziye zafikelela kwinqanaba lamazwe ngamazwe.IZiko loPhando le-Baoji le-Rare Nonferrous Metal Processing livelise ngempumelelo i-multi-core Nb-Tn superconducting umazibuthe enobubanzi obuyi-23.5 mm kusetyenziswa ucingo lwayo.Xa kuthelekiswa noomazibuthe abaqhelekileyo, olu hlobo lwemagnethi lunomthamo omncinci, ubunzima obulula kunye namandla aphezulu emagnethi;Emva kombane kunye nokusebenza okuvaliweyo, ukunikezelwa kombane akufuneki ekusebenzeni kwexesha elide.Ngokovavanyo olwenziwa ngabasebenzi baseTshayina nabaFrentshi besayensi kunye netekhnoloji kwilebhu ephezulu yeZiko loPhando leSizwe laseFransi, kwi-286.96 ℃, amandla aphakathi kwemagnethi afikelela kwi-154000 Gauss, kwaye ukusebenza kwayo kufikelela kwinqanaba lamazwe ngamazwe. .
