Graphite, types, grades, structure, properties and applications
Properties of graphite: – electrical conductivity of graphite is anisotropic (i.e. direction-dependent within the graphite). It is a good conductor of electric current in a direction parallel to the basal plane. In this case, the conductivity close to the metal. In the perpendicular direction, the conductivity is hundreds of times less.

Graphite: A mineral with extreme properties and many uses
Graphite is a mineral that forms when carbon is subjected to heat and pressure in Earth's crust and in the upper mantle. Pressures in the range of 75,000 pounds per square inch and temperatures in the range of 750 degrees Celsius are needed to produce graphite. These correspond to the granulite metamorphic facies.
