The calcinations of the precursor powders of TiO2 samples were performed at 550 degrees C, 750 degrees C and 950 degrees C. The metastable anatase form can be transformed thermally into rutile phase but the rate critically depends on the specific growth environment. The collected synthesized powders were characterized by micro Raman back-scattering spectroscopy, FTIR Spectroscopy, XRD and SEM imaging. With XRD results and also from the sample surface morphology, the size of nanocrystalline particles were determined, which showed that our samples had nano scale and also confirmed presence of pure TiO2 phases in the synthesized structures. The recorded Raman spectra confirmed that nanocrystalline anatase phase powder, which is famous for its application as photo catalyst, was produced at 550 degrees C. At 750 degrees C and 950 degrees C mixed and pure rutile phases were observed, respectively.
