phahameng bohloeki niobium machined likarolo superconducting niobium thepa

Tlhaloso e Khutšoanyane:

Lisebelisoa tsa superconducting niobium li na le lits'ebetso tse fapaneng, ho kenyeletsoa limakenete tse kholo, li-accelerator tsa likaroloana le mechini ea MRI. Bokhoni ba eona ba ho tsamaisa motlakase ka mocheso o tlase ka ho hanyetsa zero ho etsa hore e be e loketseng bakeng sa lits'ebetso tsena.

Mefuta e fapaneng ea niobium ke efe?

Niobium e teng haholo-holo ka mefuta e 'meli ea isotope e tsitsitseng: niobium-93 le niobium-95. Li-isotopo tsena li na le lipalo tse fapaneng tsa li-neutron li-nuclei tsa tsona, empa kaofela li na le litšobotsi tse tšoanang tsa lik'hemik'hale. Mabapi le sebopeho sa eona sa kristale, niobium e ka ba teng ka mefuta e fapaneng, ho kenyelletsa le mekhahlelo ea alpha le beta, ho latela mocheso le maemo a khatello.

Ntle le sebopeho sa eona sa mantlha, niobium e fumaneha ka har'a metsoako le li-alloys tse fapaneng. Ka mohlala, niobium-tin (Nb3Sn) le niobium-titanium (Nb-Ti) li atisa ho sebelisoa ho hlahisa terata ea superconducting bakeng sa likopo tse kang mechine ea MRI le li-accelerator tsa likaroloana. Li-alloys tsena li bonts'a thepa ea superconducting ka mocheso o tlase, e etsang hore e be ea bohlokoa tšimong ea superconductivity.

Ho feta moo, niobium e ka kopantsoe le litšepe tse ling ho ntlafatsa thepa ea eona bakeng sa lits'ebetso tse ikhethileng. Ka mohlala, niobium e ka kopanngoa le zirconium, tantalum kapa lintho tse ling ho etsa li-alloys tse nang le matla a ntlafetseng, ho hanyetsa kutu kapa thepa ea superconducting.

Ka kakaretso, mefuta e fapaneng ea niobium e kenyelletsa sebopeho sa eona sa mantlha, li-isotopes, meaho ea kristale, le li-alloys le metsoako e fapaneng, e 'ngoe le e' ngoe e na le thepa le lits'ebetso tse ikhethang.

Niobium e etsoa joang?

Niobium e fumanoa haholo-holo ka mokhoa o bitsoang mokhoa oa Brazilian pyrochlore. Ts'ebetso ea ho hula e na le mekhahlelo e mengata:

1. Merafo: Mohato oa pele o akarelletsa ho ntša matsoai a nang le niobium, ao hangata a amahanngoang le liminerale tse ling tse kang tantalum, tin le titanium. Brazil le Canada ke bona bahlahisi ba ka sehloohong ba ore ea niobium.

2. Tšebeliso ea borale: Ore e epiloeng e sebetsanoa ho tsepamisa liminerale tsa niobium. Hangata sena se kenyelletsa ho sila, ho sila le mekhoa e fapaneng ea karohano ho arola liminerale tse nang le niobium le likarolo tse ling tsa ore.

3. Ho hloekisoa: Motsoako o teteaneng oa niobium o tsoela pele ho hloekisoa ho tlosa litšila le ho hlahisa bohloeki bo phahameng ba niobium. Sena se ka kenyelletsa ts'ebetso ea lik'hemik'hale, leaching le ho ntšoa ha solvent ho fumana metsoako e hloekisitsoeng ea niobium.

4. Phokotso: Motsoako o hloekisitsoeng oa niobium joale o fokotsoa ho metallic niobium ka mokhoa o phahameng oa mocheso, hangata o sebelisa mekhoa e kang mokhoa oa ho fokotsa aluminothermic. Sena se fella ka tlhahiso ea tšepe ea niobium ka mokhoa oa phofo.

5. Ho kopanya: Phofo ea niobium e ntan'o kopanngoa ka mokhoa o tiileng ka mekhoa e kang phofo ea metallurgy, forging kapa mekhoa e meng ea ho etsa ho hlahisa li-ingots tsa niobium, maqephe kapa mefuta e meng e lakatsehang.

Ka kakaretso, tlhahiso ea niobium e kenyelletsa letoto la mehato ea ho ntša, ho hloekisa le ho sebetsana le lirafshoa tse nang le niobium ho fumana tšepe ea niobium e hloekileng haholo bakeng sa tšebeliso ea mekhoa e fapaneng ea indasteri.
