Niobium Powder
Niobium Powder (CAS No. 7440-03-1) inopenya grey ine nzvimbo yakakwirira yekunyunguduka uye anti-corrosion.Inotora ruvara rwebluish kana yaiswa kumhepo pamhepo tembiricha kwenguva yakareba.Niobium isimbi isingawanzoitiki, yakapfava, inogoneka, inodururira, grey-white.Iyo ine body-centered cubic crystalline chimiro uye mune yayo yemuviri nemakemikari zvimiro inofanana netantalum.Oxidation yesimbi mumhepo inotangira pa200°C.Niobium, kana yakashandiswa mukubatanidzwa, inovandudza simba.Yayo superconductive zvimiro inowedzerwa kana yasanganiswa ne zirconium.Niobium micron poda inozviwana pachayo mumashandisirwo akasiyana-siyana akadai semagetsi, kugadzira alloy, uye zvekurapa nekuda kwemakemikari ayo anodiwa, emagetsi, uye emuchina.
