  • Perovskite oxides of La1-xNaxTiO3 with mixed valence were synthesized under high-pressure and high-temperature. XRD measurement shows that the samples belong to distorted cubic perovskite structure. Volumes of samples decrease as x increases. XPS and EPR measurements indicate that Ti ions are mixed valence of +3 and +4 and vacancy of A-site ions exists. The valence state of Ti ions can be altered by high-pressure and high-temperature. IR measurement indicates that the frequency for vibration of Ti-O bond increases as x increase.
