Dense PbTiO3 ceramics consisting of submicrometer‐sized grains were prepared using the spark‐plasma‐sintering (SPS) method. Hydrothermally prepared PbTiO3 (0.1 μm) was used as a starting powder. The powder was densified to ≳98% of the theoretical X‐ray density by the SPS process. The average grain s...
