Electron microscopy of coal constituents

Lawrence A. Harris, David N. Braski, Charles S. Yust

Abstract

Studies of a high volatile bituminous coal (Hvab) have been carried out by means of a 120-kV scanning transmission electron microscope (STEM) equipped with an energy dispersion unit for elemental analyses. Sub-micron size minerals intimately associated with the organic matrix were located and identified by means of both elemental and electron diffraction analyses performed on the same particle. Particles as small as 200A in diameter were analyzed. Elemental mapping across apparently homogeneous regions observed in the electron microscope image revealed mineralogical differences within these features.
