    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 thupi lokhala ndi thupi la cubic crystalline kapangidwe kake komanso mawonekedwe ake amafanana ndi tantalum. Kutsekemera kwachitsulo mu mpweya kumayambira pa 200 ° C. Niobium, ikagwiritsidwa ntchito mu alloying, imawonjezera 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.
