Origin of graphiteGerman graphit from Classical Greek graphein, to write (see graphic): from its use as writing material
a very soft, black, hexagonal mineral of pure carbon, formed in thin plates and found in metamorphic rocks: used in making electrodes, paints, the lead of pencils, etc.
A soft crystalline allotrope of carbon, composed of graphene layers, having a steel-gray to black metallic luster and a greasy feel, used in lead pencils, lubricants, paints and coatings, and fabricated into a variety of forms such as molds, bricks, electrodes, crucibles, and rocket nozzles. Also called black lead . Also called plumbago .

- An allotrope of carbon consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely that is used as a dry lubricant and in "lead" pencils.
- Short for graphite-reinforced plastic, a composite plastic made with graphite fibers noted for light weight strength and stiffness.
- Modern tennis racquets are made of graphite, fibreglass and other man-made materials.
- A grey colour.
From German Graphit (A.G. Werner 1789), from Ancient Greek γράφω (graphō, “I write”).
- The massive graphite is very easily machined and is widely used for electrodes, dynamo brushes, lead pencils and the like.
- The " muffle," a graphite cylinder 6 in.
- YOXv13Sos, lead, and was originally employed to denote many substances containing or resembling lead; ultimately the term was applied to graphite and to molybdenum sulphide.
- Graphite and some silver ores have also been found.
- Wotton's letter of 1620, already noted, was not published till 1651 (Reliquiae Wottonianae, p. 141), but in 1658 a description of Kepler's portable tent camera for sketching, taken from it, was published in a work called Graphite, or the most excellent Art of Painting, but no mention is made of Kepler.
