Synthesis of magnesium titanates by mechanochemical method
The aim of this paper was mechanochemical preparation of magnesium titanates. Powder mixtures of starting oxides MgO and TiO2 were mechanically activated in a planetary ball mill for the time interval from 0 to 160 minutes. Structural, stereological, thermal characterizations were performed on produced powders. The effects of activation on morphology were investigated by scanning electron microscopy and particle size analyses, while the changes in the phase composition were determined by X-ray diffraction. It is determined that the first traces of MgTiO3 became detectable after 40 minutes of milling, while after 160 minutes the pure magnesium titanates were noticed. The differential thermal analyses and thermo gravimetric analysis, in temperatures range from 25 oC to 1100 oC, has been performed in order to investigate thermal behavior of the mixtures.
