Industrial Uses

Dry Lubricant

Graphite tends to form in flat layers, where the atoms link together into lattices and stack on top of each other. These layers tend to trap air and water between them, which gives graphite a lubricating effect. Although graphite powder is dry (with air and water trapped inside it), it is very effective in lubricating joints and machine parts without the need of liquids like grease and oil. Because it holds up in very high temperatures, it is good for lubricating environments that get very hot.

In Paint and E                poxy

Graphite powder's lubricity makes it a popular additive to paint, epoxy and other coatings. It can help protect surfaces from scratches and other damage. It also makes a surface less prone to friction, which makes it a popular coating for the bottoms of boats built for speed.

  Pencils 

The gray-black material in the core of a pencil that is sharpened to a point for writing is known as lead. But that material isn't lead at all. Instead, it is graphite powder blended with clay.
