    I-Niobium Powder

    I-Niobium Powder (i-CAS No. 7440-03-1) impunga ngokukhanyayo enephuzu lokuncibilika eliphezulu kanye ne-anti-corrosion. Kuthatha umbala oluhlaza okwesibhakabhaka lapho kuvezwe emoyeni emazingeni okushisa asekamereni isikhathi eside. I-Niobium iyinsimbi eyivelakancane, ethambile, ethambile, edonsayo, empunga-mhlophe. Inokwakheka kwekristalu eyi-cubic egxile emzimbeni futhi ezindaweni zayo ezibonakalayo namakhemikhali ifana ne-tantalum. I-oxidation yensimbi emoyeni iqala ku-200°C. I-Niobium, lapho isetshenziselwa i-alloying, ithuthukisa amandla. Izakhiwo zayo ze-superconductive ziyathuthukiswa uma zihlanganiswa ne-zirconium. I-Niobium micron powder izithola isezinhlelweni ezahlukene ezifana ne-electronics, i-alloy-making, kanye nezokwelapha ngenxa yamakhemikhali ayo afiselekayo, ugesi kanye nemishini.
