Abstract

High-resolution transmission electron microscope images were obtained of the layers that form when samples of coke, produced in the laboratory by pyrolysis of known organic compounds, become structurally ordered as a function of heating temperature. The images show the progressive changes that occur as amorphous material grows to form isolated layers of carbon. These then grow laterally as well as form clusters of poorly stacked layers. Increased heating changes the subparallel layers to parallel sets, initially with many discontinuities, but then to crystals having few or no such defects. By the use of images obtained with transmission electron microscopy, details of graphite crystallization can be followed in considerable detail.
