Abstract: Cenospheres prepared using fly ashes from combustion of Kuznetskii coals are investigated by Mossbauer spectroscopy, scanning electron microscopy (SEM), and thermodynamic analysis. It is shown that, in the composition range with an iron content of lower than 3.3 wt %, cenospheres involve nanosized crystalline phases, such as feldspars, ferrispinels, and pyroxenes. It is revealed that the outer and inner surfaces of the cenospheres are covered with 30- to 50-nm-thick nanofilms enriched in nanosized crystalline phases. The sizes of crystalline inclusions are estimated by etching the surface film in mineral acids with the formation of a nanosized porosity.
