ABSTRACT
Lead titanate (PbTiO3) ceramic was produced by solid state reaction via a vibratory ball milling machine and subsequent heat treatment. The effect of milling time on the particle and crystallite size of PbTiO3 powder was investigated. Powder samples were studied using particle size analyser (PSA). The annealing process was up to 1,000°C and the products were examined by X-ray diffractometer (XRD) to determine phase formation and crystallite size. It was found that the average particle size of powder initially increased due to laminated layers formation and then decreased to an asymptotic value of ~0.8 μm as the milling time extended even to a relatively longer time. Single-phase PbTiO3 were achieved at 600°C for 1 h holding time of annealing temperature. Annealing the sample of the particles at 1,000°C resulted in a dense compact and promoted the formation of particles containing nanocrystallites. The crystallite size of PbTiO3 increased as the function of temperature of annealing process.
