Abstract
Pb(Zn1/3Nb2/3)O-3 -based ceramics were thermally annealed at 700- 900 degre es C for 4 h. Both the relative dielectric constant and dissipation factor: in the vicinity of transition temperature were increased when the specimens were thermally annealed at 700-900 degrees C, but the diffusion factor was decreased. After thermal annealing, the maximum dielectric constant K-m wa s increased from about 11,000 to 26,000. These phenomena can be related to the domain wall motion and the elimination of internal stress.
