Graphite

Graphite ‒ a form of carbon **Symbol:** C **Atomic number:** 6 **International name:** Graphite **Mohs scale hardness:** 1 up to 1.5 **Crystal system:** Hexagonal **Crystal habit:** Graphite typically forms in flakes. **Description:** Graphite is a black, opaque mineral with a metallic sheen. It is an excellent conductor of both heat and electricity and is highly resistant to heat, withstanding temperatures up to 3000 ºC. The graphite structure consists of layers of hexagonally arranged carbon atoms. These layers are held together by weak van der Waals forces, allowing them to slide over each other easily, which gives graphite its lubricating properties and makes it suitable as a material in pencils for writing. **Applications:** Graphite is used in the production of pencils, electrodes, crucibles for metallurgy, lubricants, and pigments.
