Graphite is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant. This slippery quality also makes graphite a good material for pencil lead because it easily sloughs off onto paper.

graphite use as lubricant because graphite contains layers of carbon atoms the layers slide over each other easily because they are only weak force between the making graphite slippery....these electrons can move through graphite carrying charge from place to place and allowing graphite to conduct electricity
