Dielectric and a.c. conductivity properties of LiCo3/5Mn2/5VO4 ceramic are investigated. This compound is prepared by solution-based chemical method and the formation is checked by X-ray diffraction (XRD) study. XRD analysis at room temperature shows an orthorhombic phase. Frequency dependence of dielectric constant (ɛr) at different temperatures shows a dispersive behavior at low frequencies. Temperature dependence of ɛr at different frequencies indicates the transition temperature (Tc) = 235 °C, 245 °C, 257 °C and 265 °C with (ɛr)max. ∼3689, 1373, 750 and 386 for 10, 50, 100 and 200 kHz respectively. A.c. conductivity analysis indicates that electrical conduction in the material is a thermally activated process.
