Fly ash particles from the Bull Run Power Station of TVA were studied in the submicron range (average size 0.6 ..mu..m) and in the micron range (2-7 ..mu..M) by means of a scanning electron microscope (SEM) equipped with an energy-dispersive spectrometer for X-ray elemental analysis (EDX). It was found, for the fly ash studied, that the submicron particles were very similar to the particles in the micron range. Both types of particles were spherical and contained Si, K, Fe, Ti, and S as the main components. The submicron particles were distinguished only in some enrichment in sulfur content.
