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 found around the world, but Heilongjiang province, a relatively remote locale on the Russian border, is the largest single source in the world. For many there, it means big business.
Growth for Graphite? Emerging Applications May Influence Demand. Graphite is a soft, crystalline allotrope of carbon that occurs naturally in metamorphic rock. Graphite comes in three forms, crystalline flake, amorphous, and lump, and is mined from open pit and underground operations. Another common allotrope of carbon is diamond.
