Ca4.75Na0.25Al2Sb6
metalCa₄.₇₅Na₀.₂₅Al₂Sb₆ is a quaternary intermetallic compound belonging to the Zintl phase family, characterized by a mixed-cation structure combining alkaline earth (calcium), alkali (sodium), and post-transition (aluminum, antimony) elements. This material is primarily investigated in thermoelectric research contexts, where its crystal structure and electronic properties are engineered to balance electrical conductivity with low thermal conductivity for waste heat recovery applications. The compound represents an experimental composition rather than a widely commercialized material, making it relevant to researchers and engineers exploring next-generation thermoelectric materials for energy conversion rather than mainstream industrial manufacturing.
