摘要：

In the present paper, nanosized titanium dioxide (TiO2) is synthesized by wet-chemical technique, and characterized by x-ray diffraction (XRD), Fourier transform infrared reflectance (FTIR) and differential scanning calorimeter (DSC) thermograms. DSC thermogram shows a definite exothermic peak indicating the transformation from amorphous to crystalline phase. The FTIR spectra shows main peak around 1384 cm(-1), which is attributed to the Ti-O bond in both the i.e. amorphous and crystalline samples.
