Used as a precursor in the synthesis of barium-containing ceramic materials and thin films, particularly in the fabrication of high-temperature superconductors and electronic components. It serves as a barium source in sol-gel processes, enabling uniform dispersion in oxide coatings and functional layers. Its reactivity and solubility in organic solvents make it suitable for spin-coating and chemical vapor deposition techniques. Also applied in the preparation of barium titanate-based dielectrics for capacitors and electroceramic devices.
