Study of Anatase-to-Rutile Phase Transformation in Milled and Unmilled Samples
Anatase-to-rutile phase transformation was studied in milled and unmilled samples. Ball milling was carried out in two types of ball mills, planetary and tumbler, with a ball-to-powder ratio of 40:1 over 2-48 hours. First, the unmilled samples 
were heated in the furnace at various temperatures for different periods of time. The results revealed that the anatase-to-rutile transformation comp...

متن کاملKINETICS AND MECHANISM OF THE ANATASE/RUTILE TRANSFORMATION, AS CATALYZE.D BY T'ERRIC OXIDE AND REDUCING CONDITIONS Eunnsox
Traces of ferric oxide have a strong catalytic effect on both nucleation and growth phases of the transfornation of TiOz from anatase to rutile. This effect is greatly enhanced in atmospheres of low/6,. Using X-ray diffraction techniques, the kinetics of the phase transformation were studied at 1 atm. and 900 to 1000'Q for anatase mixed intimately with up to 0.2/s by weight hematite (Feroa) tn ...
متن کاملBand alignment of rutile and anatase TiO2
The most widely used oxide for photocatalytic applications owing to its low cost and high activity is TiO2. The discovery of the photolysis of water on the surface of TiO2 in 19721 launched four decades of intensive research into the underlying chemical and physical processes involved2–5. Despite much collected evidence, a thoroughly convincing explanation of why mixed-phase samples of anatase ...
