Graphite contains layers of carbon atoms. The layers slide over each other easily because there are only weak forces between them, making graphite slippery. Graphite contains delocalised electrons (free electrons).

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.

Lubricants are also used to do intercourse, it reduce the friction. And graphite have weak van der wall forces due to which it reduce the friction and it also has some brightness.

Different layers of graphite are connected together by weak Van der waal's force. This causes the layers to slip over one another. So, graphite is used as a lubricant.

The hexagonal ring structures will slip each other and vanderwal forces held between these layers like structures.so they slip each other.so it is used as lubricant.

In the Graphite covalent bond are loosely bounded and it is formed in a stack like structures due to this it has slippery surface i.e., it is used as lubricants.

Because in the graphite the covalent bonds are less tightly bounded so the graphites have smooth surface. So by this reason the graphite are used as lubricants.

Graphite contain sheets of atoms. This sheet are weakly bounded with other sheet these sheets are can easily separated. That's why graphite act as lubricant.

Because in graphite the two layes slip over each other due to less tightly coavalent bonding btween these layers. This makes graphite a lubricant.

Graphite is an allotrope of carbon but only 3 electrons satisfied. Their layers are slippery in nature. Due to this they are used as lubricating.
