Abstract

A series of samples noted TiBaX (where X = at.% of Ba) have been prepared by hydrolysis, in neutral medium from TiO2 and γ-BaCO3. These samples were calcined under air at 450 and 1150 °C then characterized by specific surface area (BET), XPS experiments, thermogravimetry (TG) and differential thermal analysis (DTA). Obtained results show that after hydrolysis, the conversion of the anatase did not take place. For the samples without barium, after calcination at 450 °C, the specific surface of TiBa0 is not modified. At 1150 °C the effect of sintering is significant; the surface of TiO2 is lower than 1 m2 g−1 and anatase structure is transformed to rutile. The addition of barium decrease surfaces of the calcined samples with 450 °C. After calcination at 1150 °C, the surface of the oxide increases with the rate of barium added. Indeed, the surfaces of TiO2 triple when 15 % of barium is added. XPS results shows presence of oxides, carbonates and oxy-carbonates. The TG analysis under H2/Ar, show that volatile specie as water of hydratation is eliminated at 100 °C.
