Mechanical and Physical Properties of PZT/xAl2O3 Ceramics Systems

Abstract

The compound of Ferroelectric nanopowrer Lead Zirconate Titanate (PZT) Pb(ZrxTi1-x)O3 was prepared using Oxalate method. Al2O3 was doped using solid state sintering method as general system PZT/xAl2O3 at (x= 0.5, 1, 1.5 vol. %). The effects of Al2O3 addition on the mechanical and physical properties of PZT ceramics were investigated. Increased Vickers Hardness with addition Al2O3 to PZT which its maximum hardness value was found for the samples containing 1vol. %Al2O3. Also, the maximum value of dielectric strength of containing 1vol.%Al2O3. This is indicating that the addition Al2O3 into PZT leads to improve dielectric properties of PZT ceramics. It is observed that the mechanical properties of the ceramics systems PZT/xAl2O3 are larger than of PZT ceramics
