Upfu hweNiobium
Niobium Powder (CAS Nhamba 7440-03-1) ine grey rakachenuruka ine poindi yakanyanya kunyunguduka uye inodzivirira ngura. Inotora ruvara rwebhuruu kana ikasangana nemhepo patembiricha yemumba kwenguva yakareba. Niobium isimbi isingawanzoonekwi, yakapfava, inonyungudika, ine ductile, ine grey-white. Ine chimiro chekristaro che cubic chiri pakati pemuviri uye muhunhu hwayo hwepanyama nemakemikari inofanana ne tantalum. Kuoxidation kwesimbi mumhepo kunotanga pa 200°C. Niobium, kana ikashandiswa mukubatanidza, inovandudza simba. Hunhu hwayo hwe superconductive hunowedzerwa kana ikabatanidzwa ne zirconium. Niobium micron powder inowanikwa mukushandiswa kwakasiyana-siyana senge zvemagetsi, kugadzira alloy, uye zvekurapa nekuda kwehunhu hwayo hwemakemikari, magetsi, uye zvemakanika.
