XPS Study on Calcining Mixtures of Brucite with Titania
In this work, we studied the phases in a Mg-Ti-O system using a 1:1 formulation of MgO:TiO<sub>2</sub>, mixing synthetic brucite of Mexican origin with TiO<sub>2</sub> microparticles of high purity, with a heat treatment at 1100 °C for 1 h. Due to its valence electrons, TiO&l...

| description | In this work, we studied the phases in a Mg-Ti-O system using a 1:1 formulation of MgO:TiO<sub>2</sub>, mixing synthetic brucite of Mexican origin with TiO<sub>2</sub> microparticles of high purity, with a heat treatment at 1100 °C for 1 h. Due to its valence electrons, TiO<sub>2</sub> can contribute to the sintering process to improve density in MgO products. The raw materials and formulation by XPS and X-RD techniques were characterized. The results demonstrate the presence of different oxidation states in titania and the formation of different oxides in the Mg-Ti-O system when mixed and calcined at 1100 °C; additionally, we estimated the formation of vacancies in the crystal lattice during the transformation from hexagonal brucite to magnesia with a cubic structure centered on the faces. Its thermal behavior is indicated by the MgO-TiO<sub>2</sub> phase diagram. |
