Used as a precursor in the synthesis of scandium-containing materials for high-performance catalysts, especially in polymerization reactions. Employed in the production of specialty ceramics and glasses with enhanced thermal and mechanical properties. Applied in research and development of solid oxide fuel cells due to its ionic conductivity when doped into certain oxides. Also utilized in the preparation of luminescent materials and phosphors for lighting and display technologies. Its high purity makes it suitable for thin-film deposition techniques such as chemical vapor deposition (CVD) or atomic layer deposition (ALD) in semiconductor and electronic applications.
