I. Cov khoom yees duab:
II. Cov lus piav qhia txog khoom
1. Khoom taw qhia:
Zoo siab hlau niobium muab, vuam cov khoom lag luam muag khoom
2. Cov ntsiab lus khoom:
Ferro niobium hmoov yog cov hlau grey tsis meej cov hmoov hlau, feem ntau yog siv hauv kev lag luam vuam, ferro niobium tsuas yog siv rau smelting siab kub (kub tiv taus) alloy, stainless hlau thiab siab zog qis alloy steel. Ferro niobium hmoov tuaj yeem txhim kho cov cuab yeej vuam hlau, ua kom lub zog thiab yas, thiab tiv thaiv xeb hlau. Rau qhov kub thiab txias tsis tshua muaj siab thiab alloys kub, niobium yog qhov tseem ceeb tsis tau, vim tias niobium tuaj yeem txhim kho lub zog siab kub, ua kom zoo dua cov nplej, tiv thaiv cov noob qoob loo ntawm qhov kub. Niobium thiab carbon sib xyaw ua ke rau tsim cov carbides, uas tuaj yeem tshem tawm cov teeb meem tsis zoo ntawm chromium carbide deposition hauv stainless hlau thiab txhim kho kev txhim kho corrosion.
