In the present study solid state reaction method is used for the synthesis of copper barium titanate (BaTiO3-Cu) composites in an inert atmosphere. Cu particles were successfully mixed with barium titanate and the resultant Cu-BaTiO3 composites with different concentrations ranging from (5-20% vol) showed high dielectric performance according to percolation phenomenon it is further seen that with the enhancement of copper content in a barium titanate powder the permittivity was significantly increased in the results shown by different techniques. Following Dielectric tests are performed for the dielectric analysis of prepared samples. Dielectric test with different temperatures and frequencies ranging from I02 Hz to 1 KHz, real and imaginary part of impedance, relative density and breakdown strength were performed. For the structural and surface morphology analysis the XRD, SEM, RAMAN and FTIR were performed, no major impurities and side reaction took place during calcination and sintering process. SEM images exhibiting uniform and homogenous grain growth of particles in sintering and resulting the formation of grains with a relatively smaller size. This work concluded that Cu-BaTiO3 is an excellent material for high dielectric constants.
