Graphite Statistics and Information - usgs.gov

Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes ("buckyballs"). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss.

Crystallography. The structure of crystals - CSIC

A crystal is a material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure. These constituents are held together by interatomic forces (chemical bonds) such as metallic bonds, ionic bonds, covalent bonds, van der Waals bonds, and others. The crystalline state of matter is the state with the highest order, ie, with very high internal ...

Graphite 101 | Focus Graphite

Graphite is the only non-metal element that is a good conductor of electricity and heat. Its softness and streak make graphite useful in making lead for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another.

RS Mines explores and extracts natural high carbon purity crystalline vein graphite from it's flagship mine, The Queen's Mine.One of the most unique materials which was discovered at The Queen's Mine was the occurrence of 'Needle' type graphite, also known as, natural highly ordered / oriented pyrolytic graphite (HOPG).

Graphite [SubsTech]

The crystalline structure of graphite consists of hexagonal rings forming thin parallel plates (graphenes). Each carbon atom is covalently bonded to three other atoms in the plate (the angle between two bonds is 120°). The outermost electron shell of a carbon atom has four valence electrons, three of which are used by the covalent bonds.
