Used as a precursor in sol-gel synthesis for preparing barium-containing oxide materials, particularly in the fabrication of barium titanate and other ferroelectric thin films. Employed in catalysis for organic transformations, including condensation and esterification reactions. Serves as a reagent in the production of advanced ceramics and electronic materials due to its ability to provide barium in a form that is soluble in organic solvents. Also utilized in the development of coatings and nanomaterials where controlled release of barium is required.
