Abstract
Dielectric measurements were performed on Pb (Zr0.53Ti0.47)O3 ceramics containing different amounts of Nd2O3 with application of high ac fie ld (0-12 kV/cm). Both the dielectric constant and dissipation factor w ere found to increase with increasing neodymium content. The compositi on having lower dopant concentration (almost-equal-to 0.5 mol%) exhibi ted excellent high-field characteristics which could be very useful in the generation of high-power ultrasonics. The effect of Zr/Ti ratios on dielectric parameters was also examined.
