Abstract

Single graphite flakes segregated from molten carbon or silicon-rich iron at 1200° to 1500°C were subjected to electron diffraction experiments. The results indicated that the well developed thick flakes are composed of one single crystal, while the thin almost colorless flakes consist of two or three single crystals oriented with the basal plane parallel to the flake surface and rotated at an angle of 15°, 18°, 22°, 25° or 28° about the C-axis. The stacking of the atomic layers in each single crystal indicates that they are α and β-type, or a more disordered structure, at each instant. Double diffraction evidence and additional electron microdiffraction observations showed that the thin single flake has an aggregate structure with two close-packed single crystals.
