Graphite - Wikipedia
Graphite (/ ˈ ɡ r æ f aɪ t /) is a crystalline allotrope (form) of the element carbon.It consists of many stacked layers of graphene, typically in the excess of hundreds of layers.Graphite occurs naturally and is the most stable form of carbon under standard conditions.Synthetic and natural graphite are consumed on a large scale (1.3 million metric tons per year in 2022) for uses in many ...
Graphite | Properties, Uses, & Structure | Britannica
Naturally occurring graphite is classified into three types: amorphous, flake, and vein.Amorphous is the most common kind and is formed by metamorphism under low pressures and temperatures. It is found in coal and shale and has the lowest carbon content, typically 70 to 90 percent, of the three types. Flake graphite appears in flat layers and is formed by metamorphism under high …
Graphite: A mineral with extreme properties and many uses - Geology.com
Graphite From Coal Seam Metamorphism ("Amorphous" Graphite) Some graphite forms from the metamorphism of coal seams. The organic material in coal is composed mainly of carbon, oxygen, hydrogen, nitrogen, and sulfur.The heat of metamorphism destroys the organic molecules of coal, volatilizing the oxygen, hydrogen, nitrogen, and sulfur.

The Mineral graphite - The Mineral and Gemstone Kingdom
Much of the commercially mined Graphite is used for pencil fillings. The "lead" filling in pencils is in fact composed of a mixture of Graphite and clay.Graphite's main function, however, is as a lubricant.It has many electrical uses, primarily because it is the only common nonmetal that is a good conductor of electricity.

Grafit – Wikipédia
A grafit a terméselemek osztályába tartozó ásvány, a szén hexagonális kristályrendszerű allotrop módosulata. Fejlett lapokkal határolt, kristályos alakban ritka, többnyire pikkelyes-leveles vagy vaskos, szemcsés, néha földes halmazokban jelenik meg.
