Effect of mass ratio of initial precursors and mechanical activation on distribution of valence electrons in Al2O3/Fe2O3 mixtures

Abstract

The energy distribution of the valence electrons in two-phase mixtures of oxides titanium and aluminum before and after mechanical activation was investigated by ultra-soft X-ray spectroscopy method. The morphology and the chemical composition of composites were studied by scanning electron microscopy. The formation of agglomerates with a strong structure of the oxides mixtures after process of mechanical activation was shown. However, analysis OKa- and AlLa-emission bands showed that no change in the distribution of valence electrons occurs. This indicates that the chemical bonds between the particles do not form, and agglomerates formation is the result of mechanical grip.
