A very strong dielectric relaxation was observed in Bi_2BaNb_2O_9 ceramic.The temperature difference between the maximum dielectric constant temperatures T_m measured at 1 kHz and 100 kHz is 65℃. which is about 2-4 times that of relaxor ferroelectrics.The possible mechanism of the anomalous dielectric relaxation was discussed.
