The sol-gel method is applied to the synthesis of Pb (Zr0.5Ti0.5) O3 particles with various post treatments. After the reaction of Pb (OAc) 2, Zr (OBu) 4 and Ti (OEt) 4 in ethanol solvent at 73°C over different reaction times, complex alkoxide is subjected to ammonia water and acetonitrile as a cosolvent at various water concentrations. The selection of reaction conditions enables the production of highly monodispersive particles with an average diameter less than 100 nm.
