  • Pb(Hf,Ti)O3 BASED HIGH PERFORMANCE POLYCRYSTALLINE PIEZOELECTRIC MATERIALS
    Publication number: 20130168596
    Abstract: A ternary polycrystalline material based on lead hafnate (PbHfO3) and having improved dielectric, piezoelectric, and/or thermal stability properties. The Pb(Hf,Ti)O3 based material can exhibit enhanced electromechanical coupling factors when compared to PZT based ceramics and can be used as high performance actuators, piezoelectric sensors and/or ultrasonic transducers. The ternary polycrystalline material can have a perovskite crystal structure with an ABO3 formula and can be characterized by a substitution of heterovalent acceptor and donor ions at A or B (Zr/Hf) sites.
