· JVASP-41881· ScS2

Scandium disulfide (ScS₂) is an inorganic ceramic compound belonging to the transition metal chalcogenide family, characterized by scandium cations bonded to sulfide anions in a layered crystal structure. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with potential applications emerging in solid-state electronics, energy storage systems, and optoelectronic devices where its unique electronic and ionic properties may offer advantages over conventional oxides or sulfides. ScS₂ is notable within materials research for its potential use in next-generation battery electrolytes, semiconductor heterostructures, and photocatalytic applications, though practical engineering adoption remains limited pending demonstration of cost-effective synthesis and scalable manufacturing.
