· JVASP-55252· Na3Ca2TaO6

Na3Ca2TaO6 is a complex oxide ceramic compound combining sodium, calcium, and tantalum in a fixed stoichiometric structure. This material belongs to the family of high-entropy and mixed-metal oxide ceramics, which are primarily of research interest for their potential in functional applications requiring specific ionic, optical, or structural properties. While not yet widely commercialized, tantalum-based oxides in this compositional space are explored for high-temperature stability, dielectric behavior, and potential photocatalytic or electrochemical applications.
