Niobium Board thiab Daim Ntawv Qhia

Niobium (Nb) yog ib lub ci grey hlau nrog lub melting point ntawm 2468 degree, boiling point ntawm 4742 degree, thiab ib tug ceev ntawm 8.57g / cm³. High-purity niobium hlau muaj ntau dua ductility, tab sis yuav harden li impurity cov ntsiab lus nce. Niobium muaj qhov tsawg heev ntes ntu rau thermal neutrons, yog li nws muaj txiaj ntsig zoo hauv kev lag luam nuclear.

SSC muab niobium dov khoom nrog tuab 0.01mm txog 10mm, suav nrog niobium phaj (board), ntawv, ntawv ci, sawb & thiab ribbon. Peb kuj tsim niobium ua rods, hmoov thiab daim hlau. Lwm cov duab muaj nyob ntawm kev thov.
