· JVASP-106839· CaPbSe2

CaPbSe₂ is a ternary ceramic compound composed of calcium, lead, and selenium, belonging to the class of chalcogenide ceramics. This material is primarily of research interest rather than established industrial production, investigated for potential applications in optoelectronic and thermoelectric devices where lead chalcogenides offer tunable band gaps and electronic properties. Engineers would consider this compound for next-generation semiconductor applications or as a model system for understanding structure–property relationships in mixed-cation lead chalcogenide systems, though commercial alternatives and lead-free variants are typically preferred due to toxicity and regulatory constraints.
