摘要

ZnTiO₃ powders with pure hexagonal phase were prepared by the sol芒芒芒gel process with Zn(NO₃)₂芒芒6H₂O and Ti(OC₄H₉)₄ materials. The thermal behavior and phase transformation of the gels were investigated by the differential scanning calorimetry芒芒芒thermogravimetry (DSC芒芒芒TG) analysis, X-ray diffraction (XRD) patterns, Fourier-transforming infrared (FT-IR) spectroscopy, and Raman scattering spectroscopy. The results revealed that pure hexagonal phase of ZnTiO₃ could be obtained at low temperature of 800 芒芒C. However, in further increased temperature above 900 芒芒C, hexagonal ZnTiO₃ would decompose into cubic Zn₂TiO₄ and rutile TiO₂.
