Abstract: Nanocrystalline perovskite phase powders like PZT or BaTiO3 were synthesized using colloidal wet chemical processing and low temperature crystallisation steps. For production of PZT powder an aqueous precursor system was synthesized. The precursor system was precipitated by using a 4 molare potassium hydroxide solution. The resulting mixture of Pb-, Zr- and Ti-hydroxide was treated in an autoclave system at temperatures up to 250 °C to promote the crystallization of the perovskite phase of PZT. BaTiO3 powders were synthesis using a solution of BaCl2 and TiCl4 which becomes heated at temperatures of about 130 °C. The powders were characterized using x-ray diffraction, TEM and specific surface measurement by BET method. Particle size distribution was measured with laser light scattering method. Influence of organic additives onto crystallization behavior and agglomeration of the PZT powders was monitored.
