| Abstract: | Piezoelectric ceramics Pb(Ni1/3Nb2/3)O3–Pb(Mg1/2W1/2)O3–Pb(Sb1/2Nb1/2)O3–Pb(Zr0.39Ti0.61)O3 with Ba(Cu1/2W1/2)O3 sintering aids were fabricated using economical industrial oxide powders and their piezoelectric, dielectric, and ferroelectric properties were investigated in order to develop low‐temperature sintering ceramics for multilayer piezoelectric actuators. A quadratic formula and the Curie–Weiss law reveal that the ceramics are typical displacive‐type ferroelectric relaxors. The ceramics sintered as low as 900°C have good piezoelectric properties of d33 = 551 pC/N, kp = 0.52, εr = 3583, tgδ = 0.02, and TC = 161°C, which is much promising to manufacture multilayer piezoelectric transducers. |
