  3. Abstract:
  4. Porous PZT-PCN ceramics were fabricated with this formula, “0.8 Pb(Zr1/2Ti1/2)O3-0.2 Pb(Co1/3Nb2/3)O3”, abbreviated as “PZTPCN” by introducing Polyvinyl chloride(PVC) and stearic acid (SA) as pore forming agents (PFA) with varied percentages (5, 10 and 15 wt%). The optimum sintering procedure was designed according to the thermogravimetric analysis of pore formers. XRD and FESEM were applied to study the formed phase and the microstructure of the system. Electrical Characterization was conducted using Piezo meter. A decrease in density reduced longitudinal piezoelectric coefficient (d33) and relative dielectric constant (ε) and enhanced hydrostatic figure of merit (dhgh) of PZTPCN ceramics. The hydrostatic figure of merit (dhgh) of 36% porous PZTPCN ceramics was four times more than that of dense ceramic
