Graphite

Graphite is a crystalline form of carbon that is a very good conductor of electricity and heat. It is a mineral that is commonly found in metamorphic and igneous rocks. Graphite has a layered structure in which the carbon atoms are arranged in hexagonal rings, with each layer being weakly bonded to the adjacent layers. This structure gives graphite its characteristic properties, such as its ability to easily slide over one another, making it a good lubricant.

Physical Properties of Graphite

• Color: Black
• Luster: Metallic
• Hardness: 1-2 on the Mohs scale
• Transparency: Opaque
• Conductivity: Good conductor of electricity and heat

Uses of Graphite

Graphite has various uses due to its unique properties:

• As a lubricant in industrial applications
• In the production of pencils and graphite rods for sports equipment
• In the manufacturing of crucibles and molds for casting metals
• In the aerospace industry for its heat-resistant properties
