Scandium (Sc)

For Al-Sc alloy, it is used, it is used in fields such as aerospace parts and sporting goods to increase the strength to aluminum is lightweight. Sc is mainly present in the form of scandium oxide (Sc 2 O 3), it is used, such as neutron filters for special optical coatings and reactors for UV detectors that transmit wavelengths of metal halide lamps, 0.25 to 5.0 [mu] m. Recently, it has been used as an electrolyte material for solid oxide fuel cells (SOFC: solid oxide fuel cell) or in addition to ceramic materials.
