Dielectric properties of Zr substituted BST ceramics

Material series with compositional formula Ba0.9Sr0.1ZrxTi1−xO3 (BSZT) were prepared by conventional solid state reaction route. XRD pattern shows that all the samples are well crystallized into perovskite structure. Tetragonality was found to decrease with increase in Zr content. Effect of substitution of Zr on dielectric constant, tangent loss and nature of transition temperature is discussed in the present paper.
