Abstract

We have studied the aging effect of bismuth sodium titanate (BNT) ceramics with point defects. With aging BNT ceramics, we have observed slight decrease in BNT permittivity. Permittivity vs. aging time is well reproduced by assumed Debyerelaxation. It is found that there are two relaxation processes in this aging effect. The diffuseness of phase transition is determined from the temperature dependence of permittivity. The diffuseness vs. composition shows the correlation clearly.
