Ukusetshenziswa kwei-niobiumNjengesengezo se-iron-based, i-nickel-based and zirconium-based superalloys, i-niobium ingathuthukisa izakhiwo zabo zamandla.Embonini yamandla e-athomu, i-niobium ifanele ukusetshenziswa njengempahla yesakhiwo se-reactor kanye nezinto zokumboza zikaphethiloli we-nuclear, kanye nokuvikela okushisayo kanye nesakhiwo semboni yezokundiza kanye ne-aerospace.I-Niobium capacitance ifana ne-tantalum capacitance, kodwa ngenxa yokuminyana okuncane kwe-niobium, umthamo weyunithi ngayinye mkhulu.I-Niobium titanium, i-niobium zirconium alloy, i-niobium tin, i-niobium aluminium germanium nezinye izinto ezihlanganisiwe eziyi-superconductive azisetshenziselwa ukudluliswa kwamandla kuphela, ukukhiqiza ugesi, ukukhiqizwa kozibuthe abakhulu, nokulawula ukuhlangana kwenuzi, kodwa futhi kusetshenziselwa amadivaysi okuzula ku-spacecraft, i-electromagnetic. imishini yokushayela yemikhumbi ye-diving enesivinini esikhulu, kanye nezitimela ze-superclass ezinesivinini esikhulu.Ukumelana nokugqwala kwe-asidi kwe-niobium kungcono kunokwe-zirconium, kodwa hhayi kuhle njengaleyo ye-tantalum.Ingasetshenziswa njengesishintshi sokushisa, i-condenser, isihlungi, i-agitator, njll. I-Niobium carbide ingasetshenziswa yodwa noma ihlanganiswe ne-tungsten carbide ne-molybdenum carbide njengoba i-forging eshisayo ifa, amathuluzi okusika, izindwani ze-turbine ye-jet injini, ama-valve, iziketi zomsila kanye ne-rocket. i-nozzle coatings.Insimbi ye-alloy equkethe i-niobium inamandla amakhulu, ukuqina okuhle kanye nokumelana nokucisha okubandayo, futhi isetshenziswa kakhulu kumapayipi kawoyela.I-lithium niobate single crystal isetshenziswa kumasethi we-TV anombala.Imvelo ye-niobium niobium iyinsimbi eyinqaba eyinqaba enensimbi empunga ecwebezelayo, futhi indawo yayo yokuncibilika ingu-2467. C. Ukuminyana kungu-8.6 g/cm3.I-Niobium ine-plasticity enhle yezinga lokushisa eliphansi futhi ingacutshungulwa emikhiqizweni ehlukahlukene eqediwe ngokucindezela okubandayo.Ukumelana nokushisa okuphezulu, amandla aphezulu, ku-1000. C nangaphezulu kusenamandla anele, ipulasitiki kanye ne-thermal conductivity.I-Superconductivity ihamba phambili emazingeni okushisa aphansi kakhulu, afana nokususa 260. Ukumelana kusondele ku-zero cishe ku-C. Ku-150. Ngezansi kuka-C, imelana nokugqwala kwamakhemikhali nokugqwala komkhathi.Iyazinzile ezixazululweni eziningi ze-asidi nosawoti ekamelweni lokushisa, kodwa i-soluble ku-hydrogen embrittlement.Ifilimu ye-oxide ezinzile yenziwa ngesikhathi se-anodization.Kumaminerali emvelo, i-niobium.Ifilimu ye-oxide ezinzile yenziwa ngesikhathi se-anodization.Kumaminerali emvelo, i-niobium ne-tantalum kuhlangana ndawonye.Amaminerali aqukethe i-niobium ne-tantalum afaka i-pyrochlore, i-niobium-tantalite, i-limonite, i-niobium-titanium-bearing rutile, i-rutile ne-niobium-tantalate placer.Enye i-steelmaking slag kanye ne-tin smelting slag nazo ziyizinsiza ezibalulekile zokucwenga i-niobium.Ukuhlukaniswa kwe-niobium ore noma i-tantalum ore kunqunywa kakhulu inani le-niobium noma i-tantalum kumaminerali.Izakhiwo ze-Nb-Tn superconducting magnetic sezifinyelele ezingeni lamazwe ngamazwe.I-Baoji Research Institute of Rare Nonferrous Metal Processing ikhiqize ngempumelelo uzibuthe we-Nb-Tn superconducting ofakwe i-multi-core Nb-Tn enobubanzi bangaphakathi obungu-23.5 mm isebenzisa intambo yayo.Uma kuqhathaniswa nozibuthe abavamile, lolu hlobo lukazibuthe lunomthamo omncane, isisindo esilula namandla amakhulu kazibuthe;Ngemuva kokuvula nokuvalwa komsebenzi, ukunikezwa kwamandla akudingekile ekusebenzeni isikhathi eside.Ngokusho kokuhlolwa okwenziwa ngabasebenzi baseShayina nabaFulentshi besayensi nezobuchwepheshe endaweni yokucwaninga ephezulu ye-National Research Center yaseFrance, ku-286.96 ℃, amandla enkambu kamagnet afinyelela ku-154000 Gauss, futhi ukusebenza kwawo kufinyelela ezingeni lamazwe ngamazwe. .
