Fa'aaogāga o Oloa Niobium
Puipuiga vevela ma mea faʻapipiʻi i vaalele ma aerospace alamanuia, paipa eletise ma isi masini masini eletise, mea e sili ona faʻaogaina, mea faʻafefe vevela ma carbide sima, ma isi.
Niobium Mea Fa'atomuaga
O a matou pepa niobium o lo'o ta'avale malulu ma fa'amama fa'amama fa'atasi ma fua fa'aitiitiga fa'apitoa e fa'amautinoa ai le fa'ameamea lelei. O laupepa taʻitasi e suʻesuʻeina maʻoti mo le tele, faʻamaeʻaina, ma le mafolafola.
O le pepa o le Niobium o le u'amea e sili ona mama (density 8.57 g/cc) ma e maualuga lona vevela (2,468ºC). O lenei meatotino e mafai ai ona tuʻuina atu fofo faʻavae i le maualuga o le vevela: maualuga atu i le 600ºC i nickel based alloys ma maualuga e 1,300ºC i niobium based alloys.
O le pepa o le Niobium e iai mea fa'aletino ma vaila'au e tutusa ma le elemene tantalum. E tete'e i le pala a'o fa'atupuina ata fa'ama'i oxide dielectric. O le uamea e amata ona faʻamaʻi vave ile ea ile 200 ºC.
I lalo ifo -264ºC, o le niobium o loʻo faʻaalia ai mea e sili atu le faʻaogaina. O lo'o fa'atinoina le maualuga o le fa'aogaina o le eletise e leai se totogi, fa'atupuina maneta ma malosi e maua mai ai fa'aoga taua i vaega e pei o su'esu'ega fa'afoma'i, su'esu'ega mea ma felauaiga.
