Summary, etc. <strong>Nickel-zinc ferrites of composition Ni<sub>x</sub>Zn<sub>1</sub><sub>-x</sub>Fe<sub>2</sub>O<sub>4 </sub>(<em>x</em>=0.66, 0.77, 0.88, 0.99) were prepared by the usual ceramic technique. The dielectric properties have been studied as a function of composition and frequency. It is observed that the values of dielectric constant є' and dielectric loss factor tanδ for samples prepared in the present work are much lower and of reduced price than those commercially obtained Ni-Zn ferrites. These low values are attributed to the presence of Si in Fe<sub>2</sub>O<sub>3</sub> powder. It has been found that the ceramic grain growth was suppressed by Si, which results in a decrease in the dielectric constant and dielectric loss factor. The dielectric constant є' and loss tangent tan δ also<em> </em>decrease as the frequency of applied <em>ac</em> electric field increases.</strong>
