Niobium Material Cov ntsiab lus thiab nws cov qauv

Niobium muaj qhov ntom ntom ntawm 8.57 g / cm³, melting point ntawm 2,477 degree thiab boiling point ntawm 4,744 degree. Niobium yog ib qho nyiaj-grey, mos thiab ductile tsawg, high-melting-point hlau, thiab tam sim no yog cov khoom tseem ceeb tshaj plaws superconducting. Niobium yog dav siv hauv kev lag luam steel, kev lag luam aerospace, kev lag luam atomic zog, kev lag luam hluav taws xob, kev kho mob thiab lwm yam kev lag luam.
