Abstract: The paper deals with synthesis of nanocrystalline La₀․₇Sr₀․₃Mn O₃ (LSMO) and BaTiO₃ (BT) powder via hydroxide co-precipitation route. The particle size of the powder is determined using Williamson Hall method and is observed to be nearly 35 nm for LSMO and 120 nm for BT. To avoid occurrence of impurity phases the composites of LSMO and BT are formed at 1273 K using Bi₂O₃ as a sintering aid. The paper focuses mainly on synthesis and dielectric properties of LSMO and BT composites. The effect of sintering aid on dielectric properties is also analyzed in this paper.
