Physical and Chemical Properties ofNiobium Phaj
Niobium yog ib qho xim grey hlau uas muaj hluav taws xob zoo thiab kev tiv thaiv corrosion, thiab tuaj yeem tiv taus corrosion los ntawm ntau cov kua qaub thiab alkali media. Lub melting point ntawm niobium yog 2468 degree, uas yog siab tshaj lub melting point ntawm cov hlau, thiab muaj zoo thermal stability ntawm high kub. Qhov ceev ntawm niobium yog 8.6 g / cm³. High-purity niobium hlau muaj ductility siab, tab sis nws yuav nyuaj dua li cov ntsiab lus impurity nce.
