Synthesis of ultrafine TiO{sub 2} by citrate gel method

Journal Article · · Materials Research Bulletin
A gel was formed when a mixture of TiOCl{sub 2} and citric acid is heated on a water bath. An ultrafine powder of TiO{sub 2} in the anatase phase is formed, when the gel was decomposed at 623 K. The anatase phase is converted into rutile phase on annealing at higher temperatures >773 K. These powders are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and surface area measurements. The average particle size obtained for anatase phase is 3.5 nm whereas it is 45 nm for rutile phase.
