Spherical shape BaNd_2Ti_5O_<14> (BNT) powders were prepared by post-treatment of the precursor powders obtained by spray pyrolysis. The mean size and geometric standard deviation of the powders prepared at a low flow rate of the carrier gas as 5 Lmin^<-1> were 0.73μm and 1.30. The powders post-treated at a temperature of 1000℃ had a single phase of BNT without impurity peaks. The BNT powders had similar compositions to that of the spray solution. Necking between the powders occurred at a sintering temperature of 1100℃. The BNT powders with spherical shape changed to the rod-like crystals after sintering at temperatures above 1200℃. The aspect ratio of the rod-like crystals increased with increasing the sintering temperatures.
