Scandium is a chemical element with symbol Sc and atomic number 21, It is a soft, silver-white transition metal with a melting point of 1541℃ and a boiling point of 2831℃. Easy to dissolve in water, can have reaction with hot water, easy to darken in air, main valence is +3 valence. It is often mixed with gadolinium, erbium, etc., with a low yield and a content of about 0.0005% in the crust. Scandium is often used to make special glass, light and high-temperature alloys.
Scandium is a kind of rare earth element, which is an irreplaceable strategic resource used in many fields of national defense and high technology, it has its own special physical and chemical properties, It has been used to prepare aluminum-scandium alloy, fuel cell, scandium sodium halogen lamp, tracer, laser crystal and other products, In special steel, nonferrous alloys, high performance ceramics, catalysts and other fields have broad application prospects.
Scandium sputtering Target is produced by vacuum melting technology, it's normally used for semiconductor and R&D purpose.
