Abstract

The influence on microstructure and electrical properties of Ta-substituted 0.80Pb(Mg_1/3Nb_2/3)O₃-0.20PbTiO₃ (0.80PMN-0.20PT) ceramics has been investigated. The grain size decreases with Ta concentration increases. The sample with 10at.% Ta substitution has dense structure and better dielectric and piezoelectric properties, with density ∼7.7g/cm³, ε_m ∼45,000, k_p ∼34% and d₃₃ ∼158pC/N. Less or more Ta doping in 0.80PMN-0.20PT ceramics is all harmful to dielectric and piezoelectric properties.
