摘要	Perovskite oxides LaTi1-xLixO3 (x=0.2, 1/3) were synthesized using high-pressure and high-temperature method. This new synthesis route has some advantages. XRD analysis showed that the x = 0.2 sample belongs to cubic perovskite-type structure and the x = 1/3 sample belongs to orthorhombic perovskite-type structure. EPR measurement indicated that Ti ions were in mixed valence of +3 and +4. IR measurement indicated that the vibration frequency and width of BO6 Octahedron stretching vibration absorption band decreases with the increasing of x. Valence of Ti ions can be altered by high-pressure and high-temperature. (c) 2006 Elsevier B.V. All rights reserved.
