Low-temperature sintering of (a-x)Pb(Zr sub(0.48)Ti sub(0.52))O sub(3)-bPb(Ni sub(1/3)Nb sub(2/3)) O sub(3)-cPb(Zn sub(1/3)Nb sub(2/3))O sub(3)-xPb(Fe sub(2/3)W sub(1/3))O sub(3) (a + b + c + x = 1, 0.06 less than or equal to x less than or equal to 0.10) ceramics were prepared through two-step synthesis process using perovskites-structured ferroelectric materials Pb(Fe sub(2/3)W sub(1/3))O sub(3) (PFW) as a sintering aid. The effects of PFW content on the densification, microstructure, phase structure, dielectric and piezoelectric properties of the ceramics were investigated. The sintering temperature was reduced from 1,180 degree C (without PFW addition) to 940 degree C when the material was PFW-doped. PFW-doping increased the sintered density and the average grain size of PFW-PNN-PZN-lead zirconate titanate ceramics. The ceramics sintered at 940 degree C for 4 h with x = 0.08 exhibited favorable properties, which were listed as follows: d sub(33) = 496pC/N, epsilon T 33/ epsilon sub(0) = 3,119, tan delta = 2.1 % and Curie temperature = 242 degree C. These values indicated that the newly developed composition might be suitable for multilayer piezoelectric devices application.
