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 matla a phahameng a 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.
