Scandium oxide Usage And Synthesis

Uses

Scandium Oxide is applied in optical coating, catalyst, electronic ceramics and laser industry. It is also used annually in making high-intensity discharge lamps. A high melting white solid used in high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition. Suitable for vacuum deposition applications.

Chemical Properties

fine white powder(s) or sintered pieces of 3–12mm; used as an evaporation material of 99.99% purity to produce fairly hard coating which is very stable, and is useful for antireflection coating on semiconductors with high index [MER06] [CER91]

Uses

Scandium oxide (Sc2O3): 2Sc3+ + 3O2- → Sc2O3. Scandium oxide is used to prepare scandium fluoride (ScF3), which is also used as an electrolyte to produce scandium metal.
