Abstract
Piezoelectric ceramics of 18PMN-41PZ-41PT were sintered by hot-pressing and normal sintering methods. The microstructure, density, P-E curve and S-E curve were also compared. The best hot-pressing condition for 18PMN-41PZ-41PT material was obtained at a temperature of 1000 °C and a pressure of 700 kg cm−2; it could achieve 99.66% theoretical density and a fine, uniform microstructure as a result of a 200–300 °C decrease in the sintering temperature. A higher coercivity was attained with the density increase. The fine, uniform microstructure also enhanced the increase in polarization and strain.
