Notes:
Sintering behavior of pure and Nb-doped barium titanate powders prepared by high-gravityreactive precipitation (HGRP) process was investigated. A thermal dilatometer was employed to monitorthe sintering shrinkage continuously during sintering. TEM and SEM were used to characterize the microstructuresof the samples. The experimental results confirmed that Nb-doped BaTiO3 ceramics sintered at1220°C for 2 h reached a larger densification of 97.0% relative density compared with 94.6% of pureBaTiO3 ceramics sintered at 1265°C for 2 h, and Nb-doped BaTiO3 ceramics had a smaller grain size(1.2μm) than that of pure BaTiO3 ceramics (2μm)
