| description | PROBLEM TO BE SOLVED: To provide a novel polycrystalline ceramic piezoelectric composition of such a composite ceramic material as ensuring best electrical characteristics of material, and to use that novel piezoelectric material in combination with other material (e.g., to form a composite material) so that it can be applied to hydrophone, robot engineering, contact pattern recognition sensor, ultrasonic transducer, and the like. SOLUTION: The piezoelectric ceramic composition comprises a solid solution of at least one dopant of 3-5 mole percent selected from a group consisting of 85.5-87.5 mole percent of niobic acid lead zinc, 9.5-9.7 mole percent of lead titanate, barium titanate and strontium titanate. The composition of the novel piezoelectric material is shown on a ternary state diagram about PZN-PT-BT and PZN-PT-ST (refer to Fig.1). COPYRIGHT: (C)2009,JPO&INPIT |
