Sažetak
Nanosized titanium dioxide powders were prepared using sol-gel procedure. The selected colloidal suspensions were stabilized with polyethylene glycol. This polymer prevented sintering of TiO_2 particles during the calcination of the starting material. X-ray powder diffraction showed that the samples, obtained up to 773 K , were a mixture of anatase and brookite. In the samples obtained at 1123 K and higher temperatures, rutile as a single phase was detected. The TGA/DTA curves were dependent on the preparation of TiO_2 samples. The samples were also characterized by Fourier transform infrared spectroscopy and laser Raman spectroscopy.
