Fa'amatalaga o oloa
Niobium foil o loʻo faʻaaogaina i: alamanuia superconducting, maualuga maualuga le vevela, alamanuia faʻaleagaina, aerospace, vailaʻau ma vailaʻau, faʻaaogaina i le gaosiga o mea faʻapipiʻi tagata, ma isi.
O le Niobium o se u'amea lanu efuefu iila e paramagnetic ma e aofia i le vaega 5 i luga o le laulau fa'avaitaimi. O le uʻamea maualuga-mama o le niobium e sili atu ona faʻafefe, ae faʻamaʻa ma faʻateleina mea le mama.
*Niobium e mautu i le ea i le vevela o le potu, ma e le atoatoa oxidized pe a mumu-vevela i le okesene. O loʻo tuʻufaʻatasia saʻo ma le sulfur, nitrogen ma carbon i le maualuga o le vevela, ma e mafai ona faʻapipiʻi faʻatasi ma titanium, zirconium, hafnium ma tungsten. E le fegalegaleai ma acids inorganic po o faavae, e le mafai foi ona solu i le aqua regia, ae e solu i le hydrofluoric acid. O faʻamaʻi faʻamaʻi o le niobium o le -1, +2, +3, +4 ma le +5, lea o le +5 o le tuufaatasiga sili ona mautu.
