Özet

The present paper describes the preparation of Pb(Zr,Ti)O-3 thin films and powders from metal chlorides by homogeneous precipitation using urea. The rate of decomposition of urea is very slow and the particles formed are very small in size (micron-sized) and highly homogeneous in composition. The coating of the films was carried out on alumina and silicon substrates in an ambient atmosphere. Heat treatment temperatures in excess of 800 degrees C were required to ensure that the perovskite phase dominated in PZT films.
