· JVASP-121946· CeAs2

CeAs2 is a ceramic compound composed of cerium and arsenic, belonging to the rare-earth pnictide ceramic family. This material is primarily of research interest rather than established in widespread industrial use, with potential applications in semiconductor research, thermoelectric materials, and high-temperature ceramic systems where rare-earth compounds offer unique electronic or thermal properties. Engineers would consider this material for advanced applications requiring rare-earth ceramic phases, though it remains in the exploratory stage compared to more conventional rare-earth oxides or established ceramic alternatives.
