摘要：
In this work, inorganic Pb(Mg1/2W1/2)(0.03)(Ni1/3Nb2/3)(x)(Zr0.5Ti0.5)(0.97-x)O-3 (x=0.02 similar to 0.12) composition ceramics were fabricated by the conventional solid state reaction method. And then their microstructure and ferroelectric properties were investigated according to the amount of PNN substitution. Small amounts of Li2CO3 and CaCO3 were used in order to decrease the sintering temperature of the ceramics. The 0.10 mol PNN-substituted PMW-PNN-PZT ceramics sintered at 920 degrees C showed the excellent physical properties of piezoelectric constant (d(33)), electromechanical coupling factor (k(p)), mechanical quality coefficient (Q(m)), and dielectric constant of 566 pC/N, 0.61, 73, and 2183, respectively.
