I-niobium powder
I-Niobium Powder (Case No. 7440-03-1) iluhlaza ompunga ngephuzu eliphakeme elincibilikayo kanye nokulwa nokubhujiswa. Kuthatha i-tint ye-bluish lapho kuvezwa umoya emazingeni okushisa asekamelweni ezikhathi ezeluliwe. I-Niobium iyi-rare, ithambile, i-muclile, insimbi emhlophe empunga. Inesakhiwo esigxile emzimbeni we-cubic crystalline nesakhiwo sayo somzimba nangamakhemikhali esifana neTantalum. I-Oxidation yensimbi emoyeni iqala ngo-200 ° C. I-Niobium, lapho isetshenziswa ku-Alloying, ithuthukisa amandla. Izakhiwo zayo ezinhle kakhulu ziyathuthukiswa lapho zihlanganiswa ne-zirconium. I-niobium micron powder ithola izicelo ezahlukahlukene ezifana ne-elekthronikhi, ukwenziwa kwe-alloy, kanye nezokwelapha ngenxa yezakhiwo zayo ezifiselekayo, zikagesi, nezemishini.
