Concentration-Pressure phase diagram for rich Zr PZT ceramics

This work reports on the systematic high pressure Raman studies in the PbZr$_{1-x}$Ti$_x$O$_3$ ($0.02 \leq x \leq 0.14$) 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.
