Graphite is widely distributed in nature as a mineral. It is usually found in the form of separate flakes, plates and clusters of different size and content. Distinguish between crystalline graphite Deposit associated with igneous rocks or schists, and cryptocrystalline graphite formed by metamorphism of coal.

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 …
The two most dominant naturally occurring forms of carbon are graphite and diamond, and these could hardly be more different in their properties: diamond is the …
Graphite was first synthesized accidentally by Edward G. Acheson while he was performing high-temperature experiments on carborundum. He found that at about 4,150 °C (7,500 °F) the silicon in the carborundum vaporized, leaving the carbon behind in graphitic form. Acheson was granted a patent for graphite manufacture in 1896, and commercial …
