explain why graphite is used as lubricant and diamond is used as abrasive ?
Asked by kunalxi | 14 Jan, 2012, 08:40: PM
Expert Answer
The graphite is made up of layers or sheets and with a solvent absorbed in between these layers they can slip over each other, thus creating the lubricant effect. The diamond is amongst one of the hardest materials we know because the carbon is bound very well to each other. Thus it can cut other things and be a drill.
