Effect of microwave sintering on the properties of Li-Zn-Ti-V ferrite

Effect of microwave sintering on the various properties of Li⁺ _0.51Zn²⁺ _0.2Ti⁴⁺ _0.2V⁵⁺ _0.01Fe³⁺ _2.08O^2- ₄ is evaluated in comparision with the conventionally sintered one. The technique is advantageous in terms of significantly reduced size of microwave kilns and the rapid heating compared to the conventional sintering technology. The product however yields higher densities, d. c. resistivity and saturation magnetization values for the microwave sintered sample. The Curie temperature is slightly lowered. Reduction in material loss during sintering and hence availability of fewer Fe²⁺ ions is one presumptions for such changes in the properties. The dielectric constant is significantly reduced possibly due to reduced space charge polarization. The temperature dependence of the dielectric properties is quite insignificant.
