✦ Synopsis

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 microwave dielectric loss and the concentration of Ti 3+ ions is discussed. Also, the quasi-chemical defect equations for the stabilization of Ti a+ ions in BaTi409-Ta205 ceramics are presented.
