Question

Why graphite is a good lubricant ?​

Answer 1

Explanation:

The greatest benefit to using graphite (rather than oil) is that the graphite leaves no sticky residue that may later attract dust. This is because the lubricating properties of graphite lie in its weak covalent bonds that allow the layers of graphite to “slide” on top of one another with very little resistance.

Answer 2

Answer:

Graphite is a good lubricant because the bonds between the the sheets are weak, graphite shows lower sharing strength under friction force.

Thus it can be used as a solid lubricant and has become one of traditional and primary solid lubricant materials.

The layers in graphite can slide over Each Other because the forces between them are weak.

This makes graphite slippery , so it is useful as a lubricant.
