Graphite is used as a lubricant in machines because it …

Graphite has a layered structure of hexagonal rings. It has one carbon atom covalently bonded to three other carbon atoms, forming a giant hexagonal molecular structure with layers held by weak Van der Waals' forces. As the Van der Waals' forces between the layers are weak, the layers can easily slide over each other when pressured and is soft.

Why Are Graphite Electrodes Used in Electrolysis? | M ...

The main reason that graphite electrodes are used in electrolysis is that graphite is an excellent conductor. The structure of graphite is such that it has a large number of electrons floating freely between the different layers of atoms (graphite bonds are formed of only three out of the four electron shells of the carbon atom, leaving the fourth electron to move freely).

WHEN SHOULD YOU USE A GRAPHITE LUBRICANT …

Last month, we chatted about ‘dry’ wax-based lubes as opposed to ‘wet’ oil-based ones. Although that blog related to bicycle chains (where a dry lube is preferred in South Africa), it does raise the subject of ‘graphite’ – another great dry lubricant..
