· Ba1 Ta1 O3

BaTaO₃ is a ceramic perovskite compound composed of barium, tantalum, and oxygen, belonging to the family of complex oxide semiconductors with perovskite crystal structure. This material is primarily investigated in research settings for its potential in high-permittivity dielectric applications, photocatalysis, and solid-state electronics, where the combination of barium and tantalum offers tunable electronic properties and chemical stability. While not yet widely commercialized in mainstream engineering, barium tantalate and related perovskites are of interest to researchers developing next-generation capacitors, optical devices, and environmental remediation systems due to their structural flexibility and favorable band-gap characteristics compared to simpler binary oxides.
