  • Piezoelectric ceramic material including processes for preparation thereof and applications therefor
    Patent number: 5527480
    Abstract: This invention relates to new ceramic piezoelectric compositions having superior electrical properties, processes for the preparation of the new piezoelectric composition and applications for the new compositions. Specifically, a solid solution composition of 85.5-87.5 molar percent lead zinc niobate, 9.5-9.7 molar percent lead titanate and 3-5 molar percent of a barium titanate dopant or strontium titanate dopant has exhibited desirable electrical properties. This specific composition is well suited for use in a 3-1 connectivity composite, which can be used as a hydrophone. These compositions may be prepared by oxide sintering techniques utilizing extremely high purity materials, or alternatively, by a sol gel process.
