| description |
Pb(Zr0.52Ti0.48)O3 piezoelectric was successfully prepared by solid state reaction method via high energy planetary ball milling. This method which implements a single firing step where the calcinations process has been skipped thus successfully controls the higher evaporation amount of PbO during sintering process. Optimization is important on sintering parameters when using a single firing process. With the optimum processing parameters and sintering conditions (temperature and duration), the excellent PZT formation and optimum electrical properties of PZT ceramics was produce. The properties of piezoelectric materials were modified by different milling duration (20, 40 and 60 hours) and sintering parameters (temperature: 1000, 1050, 1100, 1150 and 1200 °C; soaking time: 1, 2 and 3 hours). Based on the study, sample milled for 40 hours show suitable milling duration with SEM analysis promotes fine particles and densification, thus achieved an excellent dielectric and piezoelectric properties. Preliminary works have been done in order to find suitable sintering temperature and durations to obtain the best PZT formation with good piezoelectric properties. This study continued to the next phase with 40 hours and sintered at different sintering temperatures (1050, 1100, 1150 and 1200 °C) and durations (1, 2 and 3 hours).
