Abstract
In this paper we have used the hydrothermal process to synthesize Pb(Fe1/2Nb1/2)O3 ceramics at relatively low temperature. KOH alkaline solution favors the solubility of the precursors in their solid form. The obtained product was put into an autoclave and heat treated at 180°C for 24H. The recovered powder was then heat treated at different temperatures to obtain the pure perovskite phase. Reproducibility of the experiment was successfully checked. Microstructure of the samples was analysed with a scanning electron microscope (SEM), and dielectric measurements were performed using an impedance analyser (LCR, HP 4284 A) in the frequency range from 20 Hz to 1MHz.
