Abstract: Li-Zn-Ni ferrite having the compositional formula Li_0.4-0.5xZn_0.2Ni_xFe_2.4-0.5xO₄ where x=0.02≤x≤0.1 in steps of 0.02 was synthesized by the citrate precursor method and pre fired at 650^oC in a conventional furnace. It was finally given microwave sintering (MS) at 1040^OC. X- ray diffraction pattern confirmed the spinel phase structure. The theoretical and experimental density was calculated. Microstructure of the samples was examined using SEM. Room temperature dc resistivity was measured. Dielectric constant studies was carried out as a function of composition and frequency. Experimental results show resonance in the variation of dielectric loss with frequency. Possible mechanisms contributing to all the above behavior is being discussed.
 
Key words: Citrate precursor, dielectric constant, ferrites, microwave sintering.
