Graphite: A mineral with extreme properties and many uses - Geology.com
Graphite is a naturally occurring form of crystalline carbon. It is a native element mineral found in metamorphic and igneous rocks. Graphite is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity.
Graphite - Wikipedia
Graphite (/ ˈɡræfaɪt /) 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.
Graphite | Properties, Uses, & Structure | Britannica
Graphite is a mineral form of carbon that is dark gray to black, opaque, and very soft. It is used in pencils, lubricants, crucibles, foundry facings, polishes, steel furnaces, and batteries.
Graphite Mineral | Physical - Optical Properties, Uses, Occurrence
2023年4月23日 · Graphite is like diamond, It is a form of native carbon crystalline with its atoms arranged in a hexagonal structure that is opaque and dark gray to black. It occurs as hexagonal crystals, flexible sheets, scales, or large masses. It may be earthy, granular, or compact.
Graphite - Minerals Education Coalition
Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits.
Graphite | Common Minerals
Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earth’s softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils.

The Mineral graphite - The Mineral and Gemstone Kingdom
Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.
What is Graphite? - Northern Graphite
Graphite is a non-metal but has many properties of metals. It is an excellent conductor of heat and electricity and has the highest natural strength and stiffness of any material. It maintains its strength and stability to temperatures in excess of 3,600°C and is …
