· Sc2Se3

Sc₂Se₃ is a scandium selenide ceramic compound belonging to the rare-earth chalcogenide family, characterized by ionic bonding between scandium cations and selenide anions. This material is primarily investigated in research contexts for optoelectronic and photonic applications, as well as potential high-temperature structural uses, though it remains largely experimental with limited large-scale industrial deployment compared to more mature ceramic systems.
