In this research, CaCu3.1Ti4O12.1: CC(3.1)TO ceramics were prepared by a simple solid state mixed oxide method. The optimum temperature for calcination the formation of phase pure perovskite and lattice parameters "a" of unit cell close to lattice parameter in the basis JCPDS file was found about 900°C for 8 h. Phase formation was examined by X-ray diffraction technique. The sintering process was carried out at 1000, 1025 and 1050°C for 8 h. The results show that the microstructure of fracture mode for variation sintered samples change from intergranular to intragranular mode with increasing sintering temperature. The density, average grain size, Vickers hardness and dielectric constant were increased with increasing the sintering temperature.
