    OverviewPropertiesTypes and varietiesOccurrenceHistory of natural graphite useUses of natural graphiteUses of synthetic graphiteGraphite mining, beneficiation, and milling

    Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common are diamond and graphite (less common ones include buckminsterfullerene). In diamond the bonds are sp and the atoms form tetrahedra with each bound to four nearest neighbors. In graphite they are sp orbital hybrids and the atoms form in planes with each bound to three nearest neighbors 120 degrees apart.

  • Graphite: A mineral with extreme properties and many uses

    FormationGeologyIndustryOriginCompositionPropertiesStructureGraphite 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. A small amount of graphite forms by the reaction of carbon compounds in the rock during hydrothermal metamorphism. This carbon can be mobilized and deposited in veins in association with h
