Ifu ya Niobium
Ifu ya Niobium (CAS No 7440-03-1) ni imvi zijimye zifite aho zishonga kandi zirwanya ruswa.Ifata ibara ryijimye iyo ihuye numwuka mubushyuhe bwicyumba igihe kinini.Niobium ni icyuma kidasanzwe, cyoroshye, cyoroshye, cyoroshye, icyuma-cyera.Ifite umubiri-cubic kristaline yubatswe kandi mumiterere yumubiri na chimique isa na tantalum.Okiside yicyuma mu kirere itangira kuri 200 ° C.Niobium, iyo ikoreshejwe muguhuza, itezimbere imbaraga.Ibintu birenze urugero byongerewe imbaraga iyo bihujwe na zirconium.Ifu ya micron ya Niobium isanga mubikorwa bitandukanye nka elegitoroniki, gukora amavuta, hamwe nubuvuzi kubera imiti yifuzwa, amashanyarazi, nubukanishi.
