Abstract

Dislocations and low angle grain boundaries in single crystal graphite have been decorated by introducing into the crystal Cs, Br, aad FeCl3, which are known to form lamellar compounds with graphite. The existence of pockets or internal cracks, initiated at and bounded by tilt boundaries, has been inferred. Circular pockets of trapped gas bubbles are believed to nucleate at the sites of condensed vacancy disks.
