Abstract- This paper describe the synthesis of Pb (Zr0.52Ti0.48)O3 ceramic nanopowder by coprecipitation and gel-combustion routes. Metal organic and salts precursors as starting materials were used. Single phase perovskite structure of PZT was formed at temperature of 650oC after calcinations by coprecipitation and gel-combustion routes. The results of powders characterized using FTIR, SEM and XRD methods indicated that the particles sizes found to be about 70nm. The optical constants of nanopowders have been evaluated using FTIR transemittance spectroscopy and Kramers-Kronig analysis.
