CAS 7440-03-1 Niobium Nb Hlau 99.95% Niobium Hmoov
Cas7440-03-1 : kuv NiobiumNb Hlau 99.95% Niobium Hmoov
Niobium yog grey hlau, melting point 2468 ℃, boiling point 4742 ℃. Niobium ruaj khov nyob rau hauv huab cua ntawm chav tsev kub, lub liab tsis yog kiag li nyob rau hauv cov pa oxidation. Huarui muab niobium hmoov (Nb: 99% ~ 99.9%) thiab ferro niobium hmoov (Nb: 50% ~ 70%). Particle loj: 15-45um, 45-120um.80-250um ... thiab lwm yam
Daim ntawv thov:
1. Niobium yog ib qho tseem ceeb heev superconducting khoom los tsim cov capacitor siab.
2. Niobium hmoovkuj tseem siv los tsim tantalum.
3. Cov ntshiabNiobium hlau hmoovlos yog Niobium Nickel alloy yog siv los ua Nickel, Chrome thiab Hlau puag siab
kub alloy.
