How is graphite used as a lubricant? - Quora

Jan 25, 2016· Powders. Graphite powders are added ad a solid lubricant in lubricating sprays and in industrial oils used for technical applications (for hot forging/stamping and to keep lubrication in mechanical gears, for example).

The Atomic Difference Between Diamonds and Graphite ...

Diamond (left) and graphite (right) are both made of carbon atoms, but arranged in different ways. Image source. In graphite, all the carbon atoms have strong chemical bonds to three other carbon atoms, making sheets that look like chicken wire; weak forces hold the sheets together in stacks that can slide past each other easily.
