Umgubo weNiobium
I-Niobium Powder (CAS No. 7440-03-1) ingwevu ekhanyayo eneqondo eliphezulu lokunyibilika kunye nokulwa nokugqwala. Ifumana umbala oluhlaza okwesibhakabhaka xa ibekwe emoyeni kumaqondo obushushu egumbi ixesha elide. I-Niobium yintsimbi enqabileyo, ethambileyo, ethambileyo, ethambileyo, engwevu-mhlophe. Inesakhiwo sekristale ye-cubic egxile emzimbeni kwaye kwiimpawu zayo zomzimba nezekhemikhali ifana ne-tantalum. I-oxidation yentsimbi emoyeni iqala kwi-200°C. I-Niobium, xa isetyenziswa ekudibaniseni, iphucula amandla. Iimpawu zayo eziqhuba kakuhle ziyaphucuka xa idityaniswe ne-zirconium. I-Niobium micron powder ifumaneka kwiindlela ezahlukeneyo ezifana ne-elektroniki, ukwenza i-alloy, kunye nezonyango ngenxa yeempawu zayo ezinqwenelekayo zeekhemikhali, zombane, kunye neze-mechanical.
