Titanium dioxide particles are used as cosmetics, pigments, photocatalysts, adsorbents, catalytic supports, and sensors. The $TiO_2$ particles were prepared by the precipitation in TTIP/Solvent mixtures and calcined at different temperatures. The resulting materials were characterized by XRD and SEM testing techniques. The $TiO_2$ particles phase composition was determined by XRD ranging from amorphous to crystalline anatase and rutile largely proportional to the calcination temperature.
