Abstract: Barium titanate (BaTiO3) 0-3 ceramic/ceramic composite thick films (16μm) for ultrasonic transducer applications were fabricated by a modified sol-gel process. Nano-sized BaTiOj powder was dispersed in a sol-gel matrix of BaTiOj to form a 0-3 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.
