Piezoelectric properties of the porous PZT and the porous PZT composite with silicone rubber

Interconnected porous Pb (Zr0.53 Ti0.47)O3 ceramics, with controlled porosity up to 0.73, were prepared. The piezoelectric coefficient, 933, measured using a resonant method and a Berlincourt d33 meter increased as the porosity increased. The d33 and 933 of the porous PZT ceramic/ silicone rubber composite were almost the same as that of porous PZT.
