I-Niobium Powder
I-Niobium Powder (CAS No. 7440-03-1) inombala ompunga okhanyayo onephuzu eliphezulu lokuncibilika kanye nokulwa nokugqwala. Iba nombala oluhlaza okwesibhakabhaka uma ivezwa emoyeni emazingeni okushisa asekamelweni isikhathi eside. I-Niobium iyinsimbi engavamile, ethambile, eguquguqukayo, ethambile, emhlophe-empunga. Inesakhiwo sekristalu esiyisikwele esigxile emzimbeni futhi ezimpahleni zayo zomzimba nezamakhemikhali ifana ne-tantalum. Ukushiswa kwensimbi emoyeni kuqala ku-200°C. I-Niobium, uma isetshenziswa ekuhlanganiseni, ithuthukisa amandla. Izakhiwo zayo ezisebenzisa amandla aphezulu ziyathuthukiswa uma ihlanganiswa ne-zirconium. I-Niobium micron powder itholakala ezisetshenziswani ezahlukahlukene ezifana ne-elekthronikhi, ukwenza i-alloy, kanye nezokwelapha ngenxa yezakhiwo zayo ezifiselekayo zamakhemikhali, zikagesi, kanye nezemishini.
