    Carbon alone forms the familiar substances graphite and diamond. Both are made only of carbon atoms. Graphite is very soft and slippery, while diamond is one of the hardest substances known to man. Carbon, as microscopic diamonds, is found in some meteorites. Natural diamonds are found in ancient volcanic "pipes" such as found in South Africa.

  • How Is Graphite Extracted? | Sciencing

    Graphite extraction is based on the degree of weathering of the ore rock and the proximity of the ore to the surface. Around the world, graphite is mined using two techniques: the open pit method (surface quarrying) and the underground method.

  • Expandable Flake Graphite | Asbury Carbons

    Intercalation is a process whereby an intercallant material is inserted between the graphene layers of a graphite crystal or particle. After intercalation the resulting graphite material takes on new properties that are a function of the intercallant and the way it associates with the host (graphite) species.
