Scandium Oxide

Short Description:

Scandium(III) Oxide or scandia is a inorganic compound with formula Sc2O3. The appearance is fine white powder of cubic system. It has different expressions like scandium trioxide, scandium(III) oxide and scandium sesquioxide. Its physico-chemical properties are very close to other rare earth oxides like La2O3, Y2O3 and Lu2O3. It is one of several oxides of rare earth elements with a high melting point. Based on present technology, Sc2O3/TREO could be 99.999% at highest. It is soluble in hot acid, however insoluble in water.

What is Scandium Oxide used for?

Scandium Oxide, also called Scandia, gets wide applications in many industries due to its special physico-chemical properties. It is raw material for Al-Sc alloys, which gets uses for vehicle, ships and aerospace. It is suitable for the high index component of UV, AR and bandpass coatings due to its high index value, transparency, and layer hardness make high damage thresholds have been reported for combinations with silicon dioxide or magnesium fluoride for use in AR. Scandium Oxide is also 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.
