Description: This sample is a fine-grained moderator graphite with filler phase of spherical particles of Gilsocarbon (a carbon produced by heat treating gilsonite which is a naturally occurring solid hydrocarbon). The spherical shape of the gilsocarbon and the fine-grained binder phase give this graphite isotropic properties.
