Used as a precursor in the synthesis of barium-containing materials, especially in the production of thin films and ceramics via sol-gel and chemical vapor deposition methods. Commonly applied in the fabrication of superconducting materials and electroceramics where precise barium delivery is required. Also serves as a catalyst or catalyst support in organic reactions due to its thermal stability and metal coordination properties. Its solubility in organic solvents makes it suitable for homogeneous reaction systems.
