Abstract

The development of high performance piezoelectric and dielectric ceramics needs a close control of density and microstructure. Hot isostatic pressing technique using glass encapsulation method allows to produce dense and complex shape ceramics with controlled grain size. However, diffusion phenomena occur at glass ceramic interface during HIP treatment.

In this study, the glass diffusion into PZT ceramics was examined for different glass types. We noted silicon species diffusion into ceramic and also lead migration into glass resulting from PZT decomposition.

HIP carried out with diffusion barrier surrounding ceramic samples allows to prevent such a diffusion.
