matla a phahameng a 99.95% Niobium terata
Niobium terata ke sehlahisoa sa niobium se hloekileng haholo se nang le bohloeki ba 99.95%, hangata bo bitsoang terata ea niobium. Thepa e tala bakeng sa ho etsa terata ea niobium ke niobium e hloekileng haholo, e entsoeng ka lisebelisoa tsa filamentous niobium ka mekhoa ea ho lokisa polasetiki. Ka lebaka la polasetiki ea eona e ntle mochesong oa kamore, niobium e ka kena tšebetsong ea deformation joalo ka ho bilika, ho taka, ho bilika le ho kobeha ntle le ho futhumatsa.

1. Ho ntšoa ha lintho tse tala
(Niobium hangata e ntšoa ho mineral pyrochlore)
2. Ho hloekisa
(Niobium e ntšitsoeng joale e hloekisoa ho tlosa litšila le ho etsa tšepe ea niobium e hloekileng haholo)
3. Ho qhibilihisa le ho lahla
(Niobium e hloekisitsoeng e qhibilihisoa ebe e lahleloa ka har'a li-ingots kapa mefuta e meng e loketseng ts'ebetso e tsoelang pele)
4.Ho taka mohala
(Li-ingots tsa niobium joale li sebetsoa ka letoto la lithapo tsa terata ho fokotsa bophara ba tšepe le ho theha botenya ba terata bo lakatsehang)
5. Ho tlatsa
(Thepa ea niobium e ntan'o ts'oaroa ho imolla khatello leha e le efe le ho ntlafatsa ho sebetsa ha eona le ho sebetsa)
6. Phekolo ea sefahleho
(ho hloekisa, ho roala, kapa mekhoa e meng ea ho ntlafatsa thepa ea eona kapa ho e sireletsa ho senya)
7. Taolo ea boleng
- Superconducting magnets: terata ea Niobium e sebelisoa ho hlahisa limakenete tse kholo bakeng sa lits'ebetso tse joalo ka mechini ea MRI, li-accelerator tsa likaroloana, le literene tsa maglev (magnetic levitation).
- Aerospace: terata ea Niobium e sebelisoa indastering ea sepakapaka bakeng sa lits'ebetso tse joalo ka lienjine tsa sefofane, li-turbine tsa khase, le litsamaiso tsa lirokete tsa rocket ka lebaka la matla a eona a mocheso o phahameng le ho hanyetsa ho bola.
- Lisebelisoa tsa bongaka: Ka lebaka la biocompatibility ea eona le ho hanyetsa ho bola 'meleng oa motho, terata ea niobium e sebelisoa lisebelisoa tsa bongaka tse kang li-pacemaker, li-implantable defibrillators le li-implants tse ling tsa bongaka.
- Ts'ebetso e rarahaneng ea ho ntša niobium: Ts'ebetso ea ho hula le ho hloekisoa ha niobium e rarahane 'me e hloka lisebelisoa tse khethehileng le boiphihlelo. Sena se tla eketsa litšenyehelo tsa tlhahiso 'me se tla ama theko ea' maraka ea niobium.Likopo tsa litsebi: Niobium e nkoa e le ea bohlokoa ka lebaka la thepa ea eona e ikhethang, e kang superconductivity, corrosion resistance, le matla a phahameng a mocheso. Thepa ena e etsa hore e be thepa e tsebahalang bakeng sa lits'ebetso tse ikhethang liindastering tse joalo ka sefofane, bongaka le lisebelisoa tsa elektroniki, tse ka nyollang theko ea tsona.
Niobium ke tšepe e batlang e le bonolo ebile e le ductile. Ho thatafala ha eona ho tšoana le titanium e hloekileng 'me e na le boima bo batlang bo le tlase ha bo bapisoa le litšepe tse ling tse ngata. Bonolo bona le ductility tsena li etsa hore niobium e be bonolo ho e sebetsa, e lumella hore e thehoe ka mefuta e fapaneng ea libopeho le meaho ho lumellana le lits'ebetso tse fapaneng.
Niobium e sebelisoa tlhahisong ea tšepe hobane e eketsa matla, ho tiea le sebopeho sa tšepe. Ha e eketsoa ka tšepe ka tekanyo e nyane, niobium e etsa li-carbides tse ntlafatsang sebopeho sa lijo-thollo tsa tšepe le ho thibela kholo ea lijo-thollo ha tšepe e pholile. Phetoho ena e ka ntlafatsa thepa ea mochini e kang matla a eketsehileng, ho thatafala, le ho hanyetsa ho apara le mokhathala. Ho phaella moo, niobium ka ntlafatsa weldability le mocheso-a ameha libaka tsa thepa ea tšepe, ho etsa hore e bohlokoa alloying element ka mefuta e fapaneng ya dikopo tšepe, ho akarelletsa le likarolo tsa likoloi, liphaephe, thepa ea kaho, le phahameng-matla low-alloy (HSLA) steels. .
