Concentration-Pressure phase diagram for rich Zr PZT ceramics

Abstract

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