Niobium is a soft, grey, crystalline, ductile transition metal which is used as coating materials for optics for coating anti reflection film on the glass. Its melting point is 2468℃ and boiling point 4742℃. It has the characteristics of high temperature resistance, high corrosion resistance and good ductility.  Niobium sputtering target(Nb target) is the main raw material of niobium and its alloy film, which are widely used in color TFT, LCD, panel PC, optical lenses, glass coatings, electronic image, advanced touch screen, flat panel display and surface coating material for energy-saving glasses, information storage, solar cell, chemical corrosive environment and shipping enterprise.
