Flake Graphite

Pure graphite is a mineral form of the element carbon (atomic number 6) and its symbol is c. It forms in veins in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral at 1 to 2 on mohs' hardness scale. It is black and has a black streak. (streak is the color of a mineral when it is crushed to a powder). Its softness and streak make graphite useful in making f+leadf+ for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another. Mineralogists call this basal cleavage. This feature is the cause of graphite distinctive greasy feel. It is this greasy characteristic that makes graphite a good lubricant. Because it is a solid material, it is known as a dry lubricant. Graphite is the only non-metal element that is a good conductor of electricity.
