Graphite is carbon that has been heated under pressure. The next step in the process would be industrial diamonds.
Graphite occurs naturally in Madagascar, Mexico, Korea and China. It is the portion of the carbon-graphite seal face that provides the lubrication for dry running applications.
Graphite can be produced synthetically by heating petroleum coke to about 3000°F (1700°C) in an electric resistance furnace.
