Morphology and Energy Distribution of the Valence Electrons After Mechanochemical Activation SiO2/Al2O3
Journal Title: Фізика і хімія твердого тіла - Year 2015, Vol 16, Issue 3
Abstract
The analysis of morphological characteristics of nanoscale structures x-Al2O3 + y-SiO2 (x = 0,2; 0,3; 0,75; y = 0,8; 0,7; 0,25) before and after mechanical activation is hold. During the investigation of spot chemical composition is was revealed that as the consequence of mechanical activation in the structure of composites agglomerates are formed where nanoparticles of silicon and aluminum oxides are present simultaneously. The changes of the structure of morphology are confirmed by the redistribution of valence Ор-, Sisd- та Alsd electrons mixtures as a result of mechanical activation.
