Abstract
Investigations were conducted on the ferroelectric properties of Pb(Fe1/2Ta1/2)O3 ceramics, in particular, on the electromechanical properties. Dense ceramic specimens prepared by the hot-pressing technique were used in this study. At the temperature of 158 K, the following values were obtained: ε T33/ε0=1450, P r=10.8 µ C/cm2, k33=0.390 and d33=131×10-12 C/N. These values were briefly compared with those of Pb(Fe1/2Nb1/2)O3 ceramics.
