Resumen en inglés

In this study, Titanium oxyhydroxyide powder was synthetized using a modified sol-gel route. This powder is widely studied as a catalyst for CO2 desorption but is here synthesized for the Cool-SPS sintering of titania based ceramics, as a reactive precursor. It is then important to maximize its reactivity at low temperature. The influence of different synthesis parameters (base used, temperature) on the final properties of the TiO(OH)2 powder is thus investigated. The final products were characterized by XRD, FTIR, SEM, granulometry and TGA. The microstructural parameters are crucial in order to obtain a satisfying reactivity for low temperature sintering and will determine the best parameters for the synthesis of TiO(OH)2. Preliminary results concerning the sintering of TiO2 from this precursor are also reported.< Leer menos
