Abstrakt: Bi2/3Cu3Ti4O12 (BCTO) and Bi2/3Cu3Ti3.95Co0.025V0.025O12 (BCTCVO) Ceramic was synthesized by using a cost-effective novel semi-wet route method. The phase formation was confirmed by XRD analysis with traces of TiO2 and CuO phases of BCTO and BCTCVO ceramic. The average crystallite sizes of BCTO and BCTCVO ceramic were found to be 40.49 and 39.72 nm, respectively. XPS studies confirm the oxidation state of each elements in appropriate oxidation state. Elemental analysis was performed by EDS. It was observed that the maximum dielectric constant values of BCTO and BCTCVO ceramic were 3372 and 1663 at 523 K and at 1 kHz. The value of dielectric constant was observed very low at higher frequency. Tangent loss values of BCTO and BCTCVO ceramic were found 3.67 and 2.39 at 523 K and 1 kHz, respectively.
