The Al2TiO5 was synthesized by nongydrolytic sol-gel process using Ti(OC4H9)4,AlCl3 and Al(OC3H7)3 as starting materials. The IR analysis shows that there is no hydrolyzation during the process. The ICP analysis of the gel shows that the Al/Ti ratio was nearly 2. The XRD pattern of the powder sintered at different temperature shows that crystalline β-Al2TiO5 was formed at 700℃, while the powder was amorphous up to 600℃.
The vanadates of LiNi1-xMxVO4(M=Fe,Co,Ni) containing VO4 tetrahedrons were synthesized by soft chemical method through a new mild liquid route. The samples sintered at 450℃ for 3h and at 650℃ for 3h are named for LT LiNiVO4 and for MT LiNi1-xMxVO4 respectively. All of the products were measured by X ray diffraction, IR and Raman spectra respectively. In comparison with IR spectra of V2O5 and NiO, the LT LiNiVO4 has a strong and broad IR absorption band of VO4 tetrahedrons located at 600～850cm-1 with three small splitting peaks corresponding to the asymmetry stretching vibrations of V O bonds. The results of IR and Raman spectra for MT LiNi1-xMxVO4 show that the cations of Ni2+, Co2+, Fe2+ have the influences on the frequency shifts of the V O vibrations.
