Abstract

Porous piezoelectric ceramics of PZT have been newly developed to apply for ultrasonic transducers. The porous PZT was prepared from a mixture of PZT and polyvinylalcohol (PVA) powders by BURPS(Burnout Plastic Sphere) technique. Porous PZT bodies were shown a homogeneous microstructure consisting of 30 - 80 (${\mu}m$) pore size in sintered PZT bodies. The dielectric and piezoelectric properties on various PVA wt.% have investigated.
