摘要
Barium titanate (BaTiO3) ceramic/ceramic nanocomposite thick films (approximately 16 μm) for ultrasonic transducer applications were prepared by a modified sol-gel process. Nano-sized BaTiO3 powder was dispersed in a sol-gel matrix of BaTiO3 to form a composite solution. Films were prepared by spin coating and then annealed at various temperatures. The crystallization of the composite film was studied by X-ray diffraction. The dielectric permittivity and the ferroelectric properties of the film were also measured.
