Niobiun qws nrog nyiaj dawb

Niobium feem ntau pom muaj nyob rau hauv tantalum, ob lub ntsiab yog muab cais los ntawm cov feem ntawm cov feem xyaw fluoro-fractional. Nws muaj kev nplua mais ntawm 20 ppm hauv lub ntiaj teb ua kiav txhab. Niobium yuav hnov mob nrog ntau hom tsis yog-hlau rau kub txias.

Niobium thiab nws cov alloys muaj cov ntsiab lus melting siab heev thiab yog vim li no, siv cov khoom kub siab (rau kev siv thaum kub hauv 1200 C). Nws kuj yog siv los ua tus neeg sawv cev rau txhua tus hlau rau tej qhov chaw uas nws ua kom zoo zog ntawm cov khoom siv tau. Niobium kuj pom cov kev siv hauv atomic reactors vim nws qhov kev xeb hluav taws xob thiab, thaum ua ke nrog cov tin (Nb 3 Sn) los yog zirconium, nws muaj kev kawm siab ntawm kev ua siab loj.
