摘要
Lead free ceramics [(Na0.5Bi0.5TiO3)((1-x))(BiScO3)(x) X = 0 to 0.25] were prepared following the conventional mixed oxide route. The effect of incorporated BiSCO3 on the structure, lattice parameters and electrical properties of the NBT-BS system has been studied. The increase of the lattice parameters with x is linked to the increase of the mean ionic radii in the B-site of the perovskite structure. The Sc-Ti substitution increases the disorder in the cationic sublattice which involves an increase of the diffuseness of the structural phase transition at T-c.
