In this paper, some of the results of dielectric study carried out using locally produced low cost Fe2O3 powder with 0.5 wt% of Si additive are being summarized. The dielectric properties were studied as a function of composition, frequency and temperature for a series of MnxZn1-xFe2O4 ferrite. The samples were prepared by the usual ceramic technique. It was observed that the values obtained for dielectric constant ∈′ and dielectric loss factor tan δ are much lower than those normally obtained for Mn-Zn ferrite prepared by pure Fe2O3 powder. The low values are attributed to the presence of Si, which suppress the ceramic grain growth. The low dielectric loss makes these samples attractive for use at high frequencies. Each of ∈′ and tan δ increases on increasing the temperature. Abnormal dielectric behavior observed for x = 0.99 due to forced migration of Fe ions from A sites to B sites at this composition.
