Niobium, the chemical symbol Nb, is a gray metal with luster, paramagnetism, atomic number 41, atomic weight 92.90638, belonging to the VB group on the periodic table of elements. In 1801, C. harchett of England separated a new element oxide from niobate and named it columbium. The melting point is 2468 ℃, the boiling point is 4742 ℃, and the density is 8.57g/cm3. The ductility of high purity niobium is higher, but it will harden with the increase of impurity content. Niobium has a very low capture cross section for thermal neutrons, so it is very useful in nuclear industry.

Coating target: sputtering source for forming various functional films on the substrate by magnetron sputtering, multi arc ion plating or other types of coating system under appropriate process conditions. In short, the target material is the target material bombarded by high-speed charged particles. When it is used in high-energy lasers, different power densities, different output waveforms and different wavelengths of laser interact with different targets, different damage effects will be produced.
