ABSTRACT:

The paper reports details on synthesis of nanopowders of La0.7Sr0.3MnO3 (LSMO) and PbZr0.5Ti0.5O3 (PZT) via hydroxide co-precipitation route. The method is found advantageous in respect of possibilities of chemically stabilizing the average valences of the divalent Mn ions in the LSMO product. Further the hydroxide precipitates are subjected to the thermo gravimetric studies to understand the temperature of the desired phase formation. It is observed that the single phase LSMO and PZT nanopowders could be synthesized at lower temperatures with average particle size of ~ 35nm and 50 nm respectively using this method. The particle size is calculated using Williamson-Hall plots and confirmed using SEM pictures.
