Commercial kaolinite was employed to improve the dielectric property of CaCu3Ti4O12 (CCTO), and the CCTO–xwt% kaolinite samples (x=0, 5, 10, 20) were synthesized by a solid state method. X-ray diffraction results indicated that no foreign ions enter the crystal lattice of CCTO, but CuO and CaTiO3 exist as second phases in grain boundary. Scanning electron microscope measurements showed that the size...
