· JVASP-35792· ErSb2

ErSb₂ is an intermetallic ceramic compound composed of erbium and antimony, belonging to the rare-earth pnictide family of materials. This compound is primarily of research interest for its potential in thermoelectric applications and high-temperature semiconducting devices, where rare-earth antimonides are being investigated as alternatives to conventional semiconductor materials. ErSb₂ exemplifies the broader class of rare-earth pnictide ceramics, which offer potential advantages in thermal management and solid-state electronic applications, though industrial adoption remains limited compared to established ceramic and semiconductor families.
