Kushandiswa kweniobiumSekuwedzera kune iron-based, nickel-based uye zirconium-based superalloys, niobium inogona kuvandudza masimba avo. Muindasitiri yesimba reatomu, niobium inokodzera kushandiswa sechinhu chechimiro chereactor uye inovhara zvinhu zvehutsi yenyukireya, pamwe nekudzivirira kwekupisa uye zvimiro mumaindasitiri endege uye aerospace. Niobium capacitance yakafanana netantalum capacitance, asi nekuda kwediki density ye niobium, iyo capacitance per unit volume yakakura. Niobium titanium, niobium zirconium alloy, niobium tin, niobium aruminiyamu germanium uye zvimwe zvakasanganiswa superconductive zvinhu hazvingoshandiswe kutapurirana simba, kugadzirwa kwemagetsi, kugadzira magineti makuru, uye kutonga kwenyukireya fusion, asi inoshandiswawo pamidziyo yekufambisa muspacecraft, electromagnetic. propulsion midziyo yeakakwira-kumhanya diving ngarava, uye superconducting superclass yakakwira-kumhanya zvitima. Iyo asidhi yekuora kwekudzivirira ye niobium iri nani pane iyo ye zirconium, asi haina kunaka seye tantalum. Inogona kushandiswa seanopisa kupisa, condenser, sefa, agitator, etc. Niobium carbide inogona kushandiswa yoga kana musanganiswa ne tungsten carbide uye molybdenum carbide seyakapisa inofa inofa, maturusi ekucheka, jet injini turbine blades, mavharuvhu, masiketi emuswe uye roketi. nozzle coatings. Niobium-ine alloy simbi ine simba rakawanda, kusimba kwakanaka uye kutonhora kudzima kuramba, uye inoshandiswa zvakanyanya mumapaipi emafuta. Lithium niobate single crystal inoshandiswa muruvara rweTV seti. Mamiriro e niobium niobium isimbi isingawanzo shomeka ine simbi grey kupenya, uye kunyungudika kwayo i2467. C. Density i8.6 g/cm3. Niobium ine yakanaka yakaderera-kupisa epurasitiki uye inogona kugadziriswa kuita akasiyana-siyana apedzwa zvigadzirwa nekutonhora. Kudzivirira kwekushisa kwepamusoro, simba guru, pa 1000. C uye pamusoro ichine simba rakakwana, plastiki uye thermal conductivity. Superconductivity yakanakisa pakudziya kwakanyanya kwakadzika, senge minus 260. Kupokana kuri pedyo ne zero panenge C. Pa 150. Pazasi C, inopesana nemakemikari corrosion uye mhepo yemhepo. Iyo inogadzika kune akawanda acid uye munyu mhinduro pakamuri tembiricha, asi inonyungudika muhydrogen embrittlement. Iyo yakagadzikana oxide firimu inoumbwa panguva yeanodization. Mune zvicherwa zvechisikigo, niobium. Iyo yakagadzikana oxide firimu inoumbwa panguva yeanodization. Mune zvicherwa zvechisikigo, niobium uye tantalum zvinogarisana. Zvicherwa zvine niobium uye tantalum zvinosanganisira pyrochlore, niobium-tantalite, limonite, niobium-titanium-inobereka rutile, rutile uye niobium-tantalate placer. Imwe simbi yekugadzira slag uye tin smelting slag zvakare zvakakosha zviwanikwa zvekunatsa niobium. Kurongeka kwe niobium ore kana tantalum ore kunonyanya kutariswa nehuwandu hwe niobium kana tantalum muminerari. Iyo Nb-Tn superconducting magineti zvivakwa yasvika padanho repasi rose. Baoji Research Institute yeRare Nonferrous Metal Processing yabudirira mukuyedza-kuburitsa yakaisirwa multi-core Nb-Tn superconducting magineti ine dhayamita yemukati me23.5 mm ichishandisa waya yayo. Kuenzaniswa nemagineti akajairwa, iyi mhando yemagineti ine vhoriyamu diki, huremu huremu uye yakakwirira magineti simba; Mushure mekushanda kwemagetsi uye kuvhara, magetsi haadiwi kushanda kwenguva refu. Zvinoenderana nebvunzo yakaitwa neChinese neFrench vashandi vesainzi uye tekinoroji murabhoritari yepamusoro yeNational Research Center yeFrance, pa -286.96 ℃, simba repakati remagineti rinosvika 154000 Gauss, uye kuita kwayo kunosvika padanho repasi rose. .
