Electron microscopy surface study of catalysts based on ferroalloy production waste

Abstract

In the paper results of electron microscopy study of catalysts based on ferroalloy production waste from ash-slime storage of Aksu ferroalloy plant (Aksu, Kazakhstan). Thesurface morphology of catalyst granules as well pattern of surface distribution of crystallites of catalytically active metals (Fe, Cr and Mn) were described. It was shown, that during the process of catalyst obtaining, uniform porous surfaces without visible large agglomerates of metal crystallites were obtained. Distribution of metallic components was equable, particles were fine disperse, sizes of the crystallites were of one order
