Effect of Post-Heat Treatment on Physical Properties of Nanostructured TiO2 Powders Prepared by a Sol–Gel Method

Autor: H. H. Afify, Salma S. Asad, A. M. Badr, H. A. Elshaikh

Publikováno v: Journal of Electronic Materials. 49:1980-1992

A nanostructured TiO2 powder was produced by a sol–gel method. The resultant powder was sintered at different temperatures ranging from 300°C to 800°C, for a constant time of 2 h. X-ray diffraction (XRD) results indicated that an increase in sint
