Abstract

Titanium dioxide powder, in pure anatase phase with an average gain size of 20 nm, have been prepared by the microwave-assisted method. This paper investigates the influences of calcination temperature on structural and surface properties of titania. The products were characterized by powder X-ray diffraction (XRD), the Brunauer Emmett-Teller (BET) surface area measurement and the electron micrographs (SEM and TEM). The dependence of phase content, specific surface area, particle size on calcination temperature were also studied. The results of this study indicated that prepared samples are highly crystalline and pure anatase phase with the onset temperature of rutilation over 700°C.
