Ba(Zr 0.10 Ti 0.90 )O 3 (BZT10) and W + 6 substituted BZT ceramics (BZT10:W) were prepared by mixed oxide method. The effect of W + 6 addition in the BZT was evaluated by X-ray diffraction (XRD), dilatometer analysis, microstructural and dielectrical properties. When tungsten is introduced in the BZT lattice, a decrease in the grain size and shift on Curie temperature to lower value besides broadening of dielectric permittivity is evident. This is due repulsion between tungsten and their nearest neighbors leading to a structure which is tetragonal distorted. The sintering temperature is reduced when tungsten is introduced in the BZT lattice.
