· BaTaO3

Barium tantalate (BaTaO₃) is a dense ceramic compound belonging to the perovskite family, valued for its high dielectric constant and thermal stability. It is primarily used in advanced capacitor applications, microwave devices, and integrated circuit components where high permittivity and low loss characteristics are required; the material is also investigated for piezoelectric and ferroelectric applications in research settings, offering potential advantages over more conventional dielectrics in miniaturized or high-frequency electronics.
