Niobium is a transition metal element. Niobium is a lustrous grey metal. High purity niobium metal has high ductility, but will harden with the increase of impurity content. Niobium has a very low cross-section for thermal neutrons and is therefore of considerable use in the nuclear industry. Niobium is a metallic element. Niobium absorbs gas, is used as a degassing agent and is a good superconductor. Used to be called columbium. Chemical symbol Nb, atomic number 41, atomic weight 92.90638, belongs to periodic series ⅴ B group. The content of niobium in the earth's crust is 0.002%, the natural reserves of niobium in the earth's crust are 5.2 million tons, and the recoverable reserves are 4.4 million tons. The main minerals are niobite, pyroclase and black gold ore, yttrium niobium, tantalite, titanium, niobium, calcium and cerium ore.
The coating target is a sputtering source that forms various functional films on the substrate by magnetron sputtering, multi-arc ion plating or other types of coating systems under appropriate technological conditions. To put it simply, the target material is the target material of high-speed charged particles bombardment. When used in high-energy laser weapons, different power densities, different output waveforms and different wavelengths of laser interact with different targets, different killing and destruction effects will be produced. For example, evaporative magnetron sputtering coating is heated evaporation coating, aluminum film, etc. Change different target material (such as aluminum, copper, stainless steel, titanium, nickel target, etc.), can get different film system (such as super hard, wear resistant, corrosion resistant alloy film, etc.).
