## Abstract We have developed a novel route to reduce the dielectric loss of CaCu~3~Ti~4~O~12~ (CCTO) material based on the internalβbarrierβlayerβcapacitance (IBLC) model. By the partial LaβforβCa substitution the dielectric loss was suppressed reβmarkably while the giant dielectric constant still
By means of Scanning Auger Electron Spectroscopy (SAES), the presence of Ti 3+ ions in BaTi4Og-ZnO-Ta205 ceramics sintered in air was observed directly. The doublet peak structures of titanium near the 416 eV auger peak were used to identify the valence state of titanium. Correlation between the mic
