Grafiittikiteen

Grafiittikiteen refers to a crystal of graphite. Graphite is an allotrope of carbon, meaning it is one of the different forms in which an element can exist. It is known for its soft, slippery texture and its excellent electrical and thermal conductivity. Graphite crystals are composed of numerous layers of carbon atoms arranged in a hexagonal lattice. These layers are held together by weak van der Waals forces, which allows them to easily slide over each other. This property is responsible for graphite's use as a lubricant and in pencils.

The formation of graphite crystals typically occurs under high-pressure and high-temperature conditions. Natural graphite is found in metamorphic rocks, such as marble and schist. Synthetic graphite can be produced through various industrial processes, including the Acheson process, which involves heating petroleum coke or coal in an electric furnace. The purity and size of graphite crystals can vary significantly depending on their origin and formation method. These crystals can be found in a range of sizes, from microscopic to several millimeters across. Applications for graphite crystals are diverse, including in batteries, electrodes, lubricants, and refractory materials.
