Graphite have more space between their atoms and have smooth bonding that's why the graphite are always smooth in surfaces.

Graphite used in atomic reactors as a slow atomic reactions as coolent.

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).

Is a necessary component for graphite lubrication. The adsorption of water reduces the bonding energy between the hexagonal planes of the graphite to a lower level than the adhesion energy between a substrate and the graphite. Because water vapour is a requirement for lubrication, graphite is not effective in a vacuum. Because it is electrically conductive, graphite can promote galvanic corrosion.

The graphite is very soft & so graphite is used by lubricant.

These electrons can move through the graphite, carrying charge from place to place and allowing graphite to conduct electricity.

Graphite is already working as a solid lubricant.
Same as Grease is semi-solid lubricants.
