Question

why graphite is a good lubricant?​

Answer 1

The carbon atoms are strongly bonded together in sheets. Because the bonds between the sheets are weak, graphite shows lower shearing strength under friction force. Thus it can be used as a solid lubricant and has become one of traditional and primary solid lubrication materials.

Answer 2

Answer:

If you look at the structure of graphite, you will see that it is layered. There are weaker covalent bonds between these layers, hence they can easily slide over each other. Due to this, it is a lubricant, since the layers slide over each other so easily.
