“…The presence of non-stoichiometric oxygen concentrations in titanium oxides has been reported, particularly in presence of impurities (from sample preparation, or other sources), surface oxygen vacancies, or other defect states that reduce titanium dioxide to non-stoichiometric forms [63][64][65][66][67]). Botha [63], in particular, notes that the state of the oxide on titanium depends as much on the cleaning and sterilization procedure as it does the titanium substrate. While most XPS analyses agree that the elements most prominently found on titanium surfaces are Ti, O, and C, the characteristics of the oxides and the concentrations of oxygen and carbon vary significantly.…”

“…Among these nano—particles, wires, rings, combs, tetrapods of materials such as ZnO [ 4 - 8 ], WO 3 [ 9 - 12 ], and TiO 2 [ 13 - 21 ] are most desired for various semiconducting, electrochromic, and mechanical applications. TiO 2 has been reported a versatile material, required for sensors [ 22 ], optical devices [ 15 , 16 , 23 , 24 ], photocatalysis [ 25 ], photoelectrochemical [ 26 - 28 ], tribological [ 29 , 30 ], and bio-compatible surgical instruments [ 31 , 32 ]. Recently thermally evaporated TiO 2 nanowires have been examined and an efficient photoluminescence was registered in the blue region [ 13 ].…”

Controllable nanostructures in spin coated titanium oxide (TiO2) films have been achieved by a very simple means, through change of post deposition annealing temperature. Electron beam imaging and reciprocal space analysis revealed as-deposited TiO2films to be characterized by a dominant anatase phase which converts to the rutile form at 600 °C and reverts to the anatase modification at 1,200 °C. The phase changes are also accompanied by changes in the film microstructure: from regular nanoparticles (as-deposited) to nanowires (600 °C) and finally to dendrite like shapes at 1,200 °C. Photoluminescence studies, Raman spectral results, and X-ray diffraction data also furnish evidence in support of the observed solid state phase transformations in TiO2.

The mechanically activated carbothermic reduction mechanism of ilmenite has been examined by a combination of steady-state and dynamic thermal techniques coupled with X-ray diffraction. The reaction was found to proceed via an initial, rapid reduction to elemental iron and rutile, which was followed by a slow reduction of rutile to a series of oxides of the general formula Ti n O 2nϪ1 until Ti 3 O 5 was formed, which was found to be relatively stable. Iron was probably incorporated into the Ti n O 2nϪ1 lattice only for n Ͼ 3, forming mixed oxides of uncertain composition. The formation of TiC was evident at temperatures as low as 1100 ЊC, but the rate of reaction was extremely slow, presumably due to a solid-state diffusion limitation. Increasing the temperature gave increasing conversion of TiO 2 to TiC until it was the only confirmed product. The effect of iron on the later stages of reduction was removed by examining the reduction of pure rutile. It was found that the reduction of Ti 3 O 5 was enhanced by the presence of iron. The separation of iron from the titanium product proved to be high, with Ͼ90 pct of iron removed after the initial reduction. The iron removal increased slowly to almost 100 pct when elemental iron and titanium carbide were the products.
