Scandium oxide (Sc₂O₃), also known as scandium(III) oxide, is an important inorganic compound of the rare metal scandium. The material is typically supplied as a white to slightly yellowish powder and is characterized by high thermal and chemical stability.
With a melting point of approximately 2480 °C, scandium oxide is particularly suitable for high-temperature and ceramic applications. Sc₂O₃ can also be used as a starting material for the production of scandium metal and other scandium compounds.
Scandium oxide also has interesting electrical and materials-related properties. It is used in the development of solid electrolytes, ceramic materials and specialty electronic materials. In combination with other metal oxides, Sc₂O₃ can help tailor the properties of advanced technical materials.
The element scandium is used both as scandium metal and in the form of specialized compounds. While scandium metal is particularly important in specialty alloys and high-performance materials, scandium oxide is used in technical ceramics, high-temperature materials, electronics, optical applications and materials research.
