Abstract :
Thin films of lead zirconate titanate (PZT) were prepared using a modified sol-gel technique. The samples were annealed on a hotplate at 500°C. The technique yields films crystallized into (111) textured perovskite. The ferroelectric properties of the best film gave a remnant polarization value of 20.0 μC/cm2 and coercive field of 44 kV/cm. The microstructure of the film was determined to be fine grained and columnar. Permittivity for the sample was determined to be 1100. Indications of factors influencing the lowering of crystallization temperatures were observed
