Abstract
The observation of a high pressure polymorph of titania, originating f rom an anatase phase, using high energy impact vibrational ball millin g (HEIVBM) is reported here for the first time. The observed polymorph conforms to the reported high pressure modified phase of titania [ort horhombic, alpha-PbO2 (Pbcn) structure] developed by static high press ure and shock wave techniques. X-ray diffraction (XRD) and electron sp in resonance (ESR) techniques are used to characterize the polymorph.
