Niobium yog cov xim nyiaj xim uas feem ntau pom nrog tantalum, ob lub ntsiab lus tau sib cais los ntawm fractional crystallization ntawm lawv cov fluorine complexes. Niobium muaj nyob rau hauv lub ntiaj teb crust nyob rau hauv seem ib lab (ppm). Raws li ib tug ntshiab hlau, niobium yog heev reactive, thiab nws tsis kam mus corrosion yog txhim khu kev qha los ntawm tsim ib tug heev ruaj khov oxide thaum raug huab cua. Niobium reacts nrog ntau yam tsis-hlau ntawm qhov kub thiab txias.
Khoom Description
Niobium thiab nws cov alloys muaj cov ntsiab lus melting siab heev thiab yog li siv hauv cov khoom siv hluav taws xob kub kub (kub ntau tshaj 1200 degrees Celsius). Niobium kuj tseem siv los ua tus neeg sawv cev alloying rau qee cov hlau, ua kom lub zog ntawm cov khoom siv zoo heev. Niobium kuj tseem siv rau hauv atomic reactors vim nws cov corrosion kuj thiab, thaum ua ke nrog tin (Nb₃Sn) los yog zirconium, nws yog superconductive.
