Application

Scandium trioxide, a high-purity material often in the form of fine white powder or sintered pieces, is primarily used for its exceptional properties as an evaporation material with 99.99% purity. It produces a fairly hard and stable coating, making it invaluable for antireflection applications on semiconductors due to its high index. Additionally, its resistance to heat and thermal shock makes it suitable for high-temperature systems, while its role in electronic ceramics, glass composition, and as a starting material for other scandium compounds further highlights its versatility. Scandium trioxide's high melting point and ionic bonds contribute to its effectiveness in vacuum deposition applications and other advanced uses.
