    Graphite: The mineral Graphite information and pictures

    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.

    Graphite - Wikipedia

    Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

    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.
