Precious Metal Nb e nang le thepa e ntle ea mochini
Tlhaloso
Niobium, eo hangata e bitsoang Nb, ke tšepe ea bohlokoa e sebelisoang haholo mafapheng a fapaneng a kang phekolo ea meriana, sefofane le indasteri ea nyutlelie.Ke thepa e babatsehang ea mohaho oa mocheso o phahameng, oa lelapa la litšepe tse refractory.
Mofuta o mong oa niobium o atisang ho sebelisoa ke phofo ea niobium, e hlahisoang ka ho fokotsa niobium oxide ka sebōping sa mocheso o phahameng.Phofo e hlahisoang ke phofo e ntle, e bohlooho-e ntšo e nang le maemo a phahameng a bohloeki, e etsang hore e tšoanelehe bakeng sa mefuta e sa tšoaneng ea likopo.
Phofo ea Niobium e na le lintho tse ngata tse molemo, joalo ka matla a phahameng, ductility e ntle, le ho hanyetsa ho bola ha kutu.Hangata e sebelisoa lits'ebetsong tsa metallurgy tsa phofo, tse kang tlhahiso ea li-superalloys, ka lebaka la boemo ba eona bo phahameng ba ho qhibiliha le bokhoni ba ho mamella mocheso o phahameng le maemo a thata.
Lefapheng la bongaka, phofo ea niobium e sebelisetsoa ho hlahisa li-implants le lisebelisoa tsa bongaka ka lebaka la ho lumellana ha eona le ho se be chefo.E boetse e sebelisoa ha ho etsoa li-scanner tsa MRI ka lebaka la ts'oaetso ea eona e tlase ea makenete.
Lefapheng la lifofane, phofo ea niobium e sebelisetsoa ho etsa likarolo tsa enjene ea mocheso o phahameng, tse kang li-rocket nozzles le lithebe tsa mocheso, ka lebaka la tekanyo ea eona e babatsehang ea boima ba 'mele le bokhoni ba ho mamella mocheso o phahameng le libaka tse senyang.
Indastering ea nyutlelie, phofo ea niobium e sebelisoa tlhahisong ea lithupa tsa mafura le likarolo tsa reactor ka lebaka la bokhoni ba eona ba ho mamella mocheso o phahameng le tikoloho e senyang.
Ka kakaretso, phofshoana ea niobium ke lisebelisoa tse ngata le tsa bohlokoa tse fanang ka thepa e ikhethang 'me e ka sebelisoa mefuteng e mengata ea likopo.
