Abstract

This work reports on systematic high-pressure Raman studies of the PbZr1-xTixO3 (0.02 less than or equal to x less than or equal to 0.14) ceramics performed at room temperature. The pressure dependence of the Raman spectra reveals the stable phases of the material under pressure variation. The results allowed us to propose a concentration-pressure phase diagram for the Zr-rich PZT system up to pressures of 5.0 GPa.
