Ca4 Ta2 Sb2 O12
semiconductor· Ca4 Ta2 Sb2 O12
Ca₄Ta₂Sb₂O₁₂ is a complex oxide ceramic semiconductor composed of calcium, tantalum, antimony, and oxygen. This is a research-phase compound belonging to the family of mixed-metal oxides, which are being explored for their electronic and ionic transport properties in solid-state applications. While not yet widely commercialized, materials in this compositional class show promise in energy storage, electrochemical devices, and specialized optoelectronic applications where the combination of structural stability and semiconducting behavior offers advantages over conventional single-phase ceramics or perovskite alternatives.
