Explanation:
Detailed explanation-1: -Graphite is used as a lubricant since ancient times. The graphite has a layered structure that is held together by weak van der Waal forces. As it is easy to break van der Waal forces thus the layers slide on one another. Due to this slippery nature, graphite is used as a lubricant.
Detailed explanation-2: -Graphite is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant.
