Used primarily in research and development, this compound serves as a precursor for synthesizing scandium-based materials. It is utilized in the preparation of catalysts for organic reactions, especially in polymerization processes where scandium ions enhance reaction efficiency and selectivity. In solid oxide fuel cells, it contributes to the development of electrolyte materials due to scandium’s ability to stabilize certain crystal structures. It also finds use in the production of specialty ceramics and luminescent materials, where scandium doping improves thermal and optical properties. Due to its reactivity and metal content, it is explored in environmental chemistry for metal recovery and ion-exchange applications.
