Abstract
This work reports on the systematic high pressure Raman studies in the PbZr1-xTixO3 (0.02 ≤ x ≤ 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 rich Zr PZT system up to pressures of 5.0 GPa.
