Scandium oxide Chemical Properties,Usage,Production
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.
Structure
Sc₂O₃ (Scandium oxide) is a Corundum-like structure and crystallizes in the cubic Ia̅3 space group. There are two inequivalent Sc³⁺ sites. In the first Sc³⁺ site, Sc³⁺ is bonded to six equivalent O²⁻ atoms to form a mixture of corner and edge-sharing ScO₆ octahedra. The corner-sharing octahedral tilt angles are 54°. All Sc-O bond lengths are 2.12 Å. In the second Sc³⁺ site, Sc³⁺ is bonded to six equivalent O²⁻ atoms to form a mixture of distorted corner and edge-sharing ScO₆ octahedra. The corner-sharing octahedral tilt angles range from 53-54°. There is a spread of Sc-O bond distances ranging from 2.09-2.17 Å. O²⁻ is bonded to four Sc³⁺ atoms to form a mixture of distorted corner and edge-sharing OSc₄ trigonal pyramids.
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.
Definition
Scandium oxide has an extremely high melting point and is therefore likely to be an ionic compound, meaning its particles are joined by ionic bonds.
Preparation
Scandium Oxide, SC2O3: It is obtained readily by heating the salts such as scandium carbonate and scandium nitrate.
Sc2(CO3)3-Heat->Sc2O3+3CO2
4Sc(NO3)3-->2Sc2O3+12NO2+3O2
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.
Solubility in water
The oxide of scandium is not soluble in water but it can be soluble in hot acids but sometimes it reacts also. But the scandium oxide is amphoteric as if the compound can react with acid as well as a base then the compound is said to be amphoteric.
