Abstract
Niobium-doped Pb(Zr0.53Ti0.47)O3 (PZTN) ceramics were prepared by the conventional(mixed oxides) method, modified by the addition of a PZT colloid of the same composition. The colloidal precursor was prepared using a coprecipitation method. Such an addition produced a significant improvement in the sinterability of a conventionally prepared PZTN powder and the sintering temperature was reduced, achieving a density ⩾98% theoretical density at 1075 °C for 2 h. The measured piezoelectric properties were as high askp = 0.62 andd33 = 330 ×10−12CN−1.
