Molecular structure of graphite. Graphite consists of a ring of six carbon atoms closely bonded together hexagonally in widely spaced layers. The bonds within the layers are strong but the bonds between the layers are less in number and therefore are weaker. Graphite is the stable form of carbon – diamonds at or near the Earth's surface are ...
This naturally occurring mineral is a form of crystalline carbon. This non-metallic carbon polymorph is found lying deep within metamorphic and igneous rocks.

Graphite comes naturally and abundantly in three different forms: 'crystal' flake, lump and amorphous. Only high purity (>99.9 per cent) graphite flake is capable of producing the level of electrical conductivity needed to be considered 'battery-grade'. About one million tonnes of the mineral is sold annually worldwide.
Graphite occurs naturally in the earth and, under standard conditions, is the most stable form of carbon [1]. This mineral is used in a diverse number of applications from pencils to lubricants and batteries to other more extreme applications, such as nuclear fusion and the Wendelstein 7-X fusion reactor [2]. Here, you will learn about:

Graphite is a form of pure carbon that normally occurs as black crystal flakes and masses. It has important properties, such as chemical inertness, thermal stability, high electrical conductivity, and lubricity (slipperiness) that make it suitable for many industrial applications, including electronics, lubricants, metallurgy, and steelmaking.
Graphite facts. Graphite is a non-metallic mineral that has properties similar to metals, such as a good ability to conduct heat and electricity. Graphite occurs naturally or can be produced synthetically. Purified natural graphite has higher crystalline structure and offers better electrical and thermal conductivity than synthetic material.
