Abstract
Abstract In this study, the researcher developed porous lead zirconate titanate-lead cobalt niobate 0.8Pb (Zr1/2Ti1/2)O3-0.2Pb(Co1/3Nb2/3)O3 (PZT-PCN) piezoelectric ceramics with varying porosity using PVC Stearic Acid (SA) and PMMA as pore forming agents (PFA) by burnable plastic sphere process (BURPS). The study investigated the effect of PFA on the microstructure, dielectric and piezoelectric properties pertaining to porous PZT-PCN ceramics. The density decreased as the content of pore formers increased. This resulted in increasing of the porosity. The values of both relative permittivity (Ɛr) and longitudinal piezoelectric coefficient (d33) were shown to have decreased by increasing the porosity. The results showed the hydrostatic of merit (dhgh) of PZT-PCN with density of about 4.4 g/cm3 reached 2732 × 10−15 m2/N, which demonstrates that porous PZT-PCN ceramic is a promising material for biomedical diagnostic devices.
