How graphite is used as a lubricant?

Rajdeep said:   9 years ago
Graphite is a solid lubricant.

SUPRIT KUMAR RATH said:   9 years ago
Yeah,

According to me, Graphite has very smooth surface. It has one free (delocalysed) electron. Moreover, the carbon atoms present makes it's slippery.

So, It is used as a solid lubricant.
