Titanium dioxide shows polymorphism on heating at high temperature. This strongly depends on temperature and duration of heating. When amorphous titania pulp was heated at different temperatures and time between 900 and 1000 degrees C, anatase-rutile transformation occurred. This transformation under the influence of different percentages of NiO was studied by preparing samples by two different methods. The transformation temperature was found to be lowered in the presence of the above metal oxide. Also the method of preparation of metal oxide-doped TiO2 affects the polymorphism. The different phases of TiO2 were determined using powder XRD. Other methods such as chemical analysis, scanning electron microscopy, surface area measurements and crystallite size calculation were used for the characterization of the samples.
