· Ba3 Sr1 Ta2 O9

Ba₃Sr₁Ta₂O₉ is a complex oxide ceramic compound belonging to the perovskite family, combining alkaline earth metals (barium and strontium) with tantalum in a high-temperature ceramic matrix. This material is primarily investigated in research contexts for its potential use as a dielectric or electronic ceramic, leveraging the stable crystal structure and thermal properties characteristic of tantalate-based compounds. Its development is driven by applications requiring high-temperature stability, low dielectric loss, or specialized electrical properties in microwave and RF devices.
