Abstract

The compound of Ferroelectric nanopowrer Lead Zirconate Titanate (PZT) Pb(Zr x Ti 1-x)O 3 was prepared using Oxalate method. Al 2 O 3 was doped using solid state sintering method as general system PZT/ x Al 2 O 3 at (x= 0.5, 1, 1.5 vol. %). The effects of Al 2 O 3 addition on the mechanical and physical properties of PZT ceramics were investigated. Increased Vickers Hardness with addition Al 2 O 3 to PZT which its maximum hardness value was found for the samples containing 1vol. %Al 2 O 3. Also, the maximum value of dielectric strength of containing 1vol.%Al 2 O 3. This is indicating that the addition Al 2 O 3 into PZT leads to improve dielectric properties of PZT ceramics. It is observed that the mechanical properties of the ceramics systems PZT/ x Al 2 O 3 are larger than of PZT ceramics.
