Phases and Dielectric Properties of Relaxor Ferroelectric Composite Ceramics

Zhen-Xin Yue

Abstract

The relaxor ferroelectric ceramics in Pb(Zn1/3Nb2/3)O3 -BatTiO3-PbTiO3 system were prepared by mixed-sintering method. SRD studies revealed that the ceramics have diphasic composite structure. The dielectric properties of composite ceramics were studied, and the results showed that the temperature and frequency dependencies of capacitance as well as aging behavior can be improved with composite structure. Thus, a temperatire- stable PZN composite ceramic with excellent dielectric properties was obtained.
