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 …
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 is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. Graphite, also called plumbago or black lead, mineral consisting of carbon. Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets. Graphite thus ...
Graphite. Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.

Molybdenite is the most prevalent molybdenum-bearing mineral, and is named after that element. Prior to the discovery of molybdenum as a separate element in 1778 by Karl Wilhelm Scheele, Molybdenite was thought to be Graphite or a lead ore.In fact, the word molybdos means "lead" in ancient Greek. Molybdenite forms in two distinct crystal …
A natural form of elemental carbon, it is also the most stable form under natural conditions. Unlike diamond, the other major natural form of carbon, graphite is formed from sheets of carbon atoms arranged in a hexagonal grid, with only weak bonds between the layers, making graphite a very soft material as these layers are easy to part.
Natural graphite is greener than synthetic, leading auto makers to turn to mines for the mineral.
