Used primarily in research and specialized chemical synthesis, this compound serves as a catalyst in organic reactions, particularly in polymerization processes. It is also employed in the production of scandium-containing materials for high-performance alloys, especially in aerospace and defense industries. Its role in electrolytic processes allows for the deposition of scandium metal, which enhances the strength and thermal stability of aluminum alloys. Additionally, it finds use in the development of solid oxide fuel cells and certain types of lighting systems due to the unique electronic properties it imparts when doped into host materials.
