Niobium Powder
Niobium Powder (CAS No. 7440-03-1) ndi imvi yopepuka yokhala ndi malo osungunuka kwambiri komanso anti-corrosion. Zimatengera kupendekera kwa bluish zikakumana ndi mpweya pamalo otentha kwa nthawi yayitali. Niobium ndi chitsulo chosowa, chofewa, chosasunthika, chodumphira, chotuwa-choyera. Ili ndi mawonekedwe amtundu wa cubic crystalline wokhala ndi thupi komanso mawonekedwe ake amthupi ndi mankhwala amafanana ndi tantalum. Kutsekemera kwachitsulo mu mpweya kumayambira pa 200 ° C. Niobium, ikagwiritsidwa ntchito mu alloying, imalimbitsa mphamvu. Ma superconductive ake amakula akaphatikizidwa ndi zirconium. Niobium micron powder imapezeka muzinthu zosiyanasiyana monga zamagetsi, kupanga alloy, ndi zamankhwala chifukwa chamankhwala ake ofunikira, magetsi, ndi makina.
