Introduction In sonar system, underwater transducer is an important component, and transducer element material is the key to development of underwater transducer [1]. 1-3 piezocomposites are one kind of the most popular new piezoelectric materials due to its many advantages, such as lower acoustic impedance, quality factor, planar electromechanical coupling factor and dielectric constant [2], so it is excellent for fabricating a sensitive receiving transducer that offers quite wide frequency band [3].
