    Umgubo weNiobium

    I-Niobium Powder (i-CAS No. 7440-03-1) i-gray ekhanyayo kunye neqondo eliphezulu lokunyibilika kunye ne-anti-corrosion. Ithatha i-tint bluish xa ibonakaliswe emoyeni kumaqondo obushushu begumbi ixesha elide. I-Niobium inqabileyo, ithambileyo, ithambileyo, i-ductile, intsimbi engwevu-emhlophe. Inomzimba ogxile kwi-cubic crystalline structure kunye neempawu zayo zomzimba kunye neekhemikhali zifana ne-tantalum. Ukufakwa kwesinyithi kwi-oxidation emoyeni kuqala kwi-200°C. I-Niobium, xa isetyenziswe kwi-alloying, iphucula amandla. Iimpawu zayo ze-superconductive ziphuculwe xa zidibene ne-zirconium. I-Niobium micron powder izifumana kwizicelo ezahlukeneyo ezifana ne-electronics, i-alloy-making, kunye nezonyango ngenxa yeekhemikhali ezinqwenelekayo, umbane kunye neempawu zoomatshini.
