| | 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]
High-purity scandium oxide (i.e., 99.0 to 99.99 wt.% Sc) is an initial raw material used to produce a metallic scandium.
The growth of scandium oxide produces a smooth surface as evident by the AFM RMS roughness of 0.5 to 0.8 nm.The growth rate of the scandium oxide was 0.67nm/min for Tsc=1130℃ and 1.25nm/min for Tsc=1170℃. | | 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. | | Uses | Scandium oxide is resistant to heat and thermal shock, hence finds use in high-temperature systems. Further, it is used in electronic ceramics and glass composition. It is used as a starting material for the preparation of other scandium compounds. In addition to this, it has vacuum deposition applications. | | Uses | Suitable for vacuum deposition applications | | Preparation | Scandium Oxide, SC2O3: It is obtained readily by heating the salts such as scandium carbonate and scandium nitrate.

Scandium oxide is a white powder. It is more basic than aluminium oxide but less basic than calcium oxide. It absorbs carbon dioxide from the air.
It has the MnO3 structure.The crystal structure of scandium oxide is Bixbyite , which is an FCC array of scandium atoms with oxygen occupying 44 of the tetrahedral sites. |
