Ca₄.₉₅Na₀.₀₅Al₂Sb₆ is an experimental intermetallic compound belonging to the alkaline earth metal–pnictide family, specifically a calcium-based antimonide with minor sodium doping. This material is primarily of research interest for thermoelectric applications, where the combination of low thermal conductivity with controlled electrical properties makes it a candidate for solid-state heat-to-electricity conversion devices. The material's structure and composition are tailored to reduce phonon transport while maintaining adequate charge carrier mobility, a key design principle in modern thermoelectric materials research.
