Abstract : Synthesis of lead zirconium titanate by a simple, low-energy consumption hydrothermal means is being reported. The precursor materials have been chosen and the method is tailored so that the process becomes economical and offers low lead loss. The synthesised powders have been analysed by FTIR, XRD, SEM, TEM, and TGA. The results show the formation of tetragonal PZT nanoparticles with an average yield of ~75 per cent. On the basis of FTIR, the product formation is understood to proceed via the formation of a three metal cation hydroxide complex, that under hydrothermal treatment undergoes conversion directly to form the tetragonal phase of lead zirconium titanate.
