· JVASP-49984· BaTeO4

Barium tellurate (BaTeO₄) is an inorganic ceramic compound composed of barium, tellurium, and oxygen. It belongs to the tellurate ceramic family and is primarily of interest in materials research rather than high-volume industrial production. This compound is investigated for potential applications in optical materials, solid-state ion conductors, and specialized electronic ceramics where tellurium-based oxides offer unique dielectric or photonic properties unavailable in more conventional oxides.
