Basic knowledge of niobium
The chemical symbol of niobium is Nb, its atomic number is 41, and its atomic weight is 92.90638. It belongs to the group ⅤB of the periodic system. In 1801, British C. Hatchett separated an oxide of a new element from niobite and named the element columnum (Chinese translation: A kind of). Niobium is an off-white metal with a melting point of 2468 ° C, a boiling point of 4,742 ° C, and a density of 8.57 g / cm3. Niobium is a shiny gray metal with paramagnetism and belongs to Group 5 on the periodic table. High-purity niobium metal has higher ductility, but will harden with increasing impurity content. The capture cross section of niobium for thermal neutrons is very low, so it is quite useful in industry.
Because niobium products are more expensive, they need to be customized according to customer requirements.
