Titanium oxide nanoparticles were synthesized using Titanium Tetraisoproproxide and varied pH values.  The nanoparticles were left in solution from times varying between two hours and two months.  The synthesized nanopowders were then heated to temperatures between 80� C and 750� C varying between one and two hour time increments at each temperature.   Differential Scanning Calorimetry (DSC) was used to further refine the heating ranges to get a more accurate range at which the nanopowders changed phase.  After being synthesized, each of the nanopowders were characterized according to their size, composition and phase, and absorbance properties using Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), and UV-Vis Spectroscopy, respectively.  The spectra and diffraction patterns were used to determine the temperature required to induce a phase change from the amorphous to anatase structure and anatase to rutile structures.    The resulting spectra were compared to literature spectra to ensure that pure samples of each species of nanopowder were obtained.
