The dense Pb(Zr0.52Ti0.48)O3 (PZT) piezoelectric ceramics have been prepared at a low temperature by a spark plasma sintering (SPS) method without excess PbO addition and their structural features including domains were systematically investigated. The fine microstructure consisting of submicrometer-sized grains as well as relative density reaching 99% was achieved by sintering at 950°C which is 400°C lower than that of pressureless sintering (PLS). Transmission electron microscopy (TEM) results confirmed that the sintered specimen contained very dense domain structures inside each grain, showing the nanoscaled single-domains even at the small grains (below 100 nm). The SPS-processed PZT exhibited better piezoelectric properties than those of the PLS-processed one, which is attributed to its fine-microstructural feature.
