When graphite is in high enough concentrations, these rocks can be mined, crushed to a particle size that liberates the graphite flakes, and processed by specific gravity separation or froth flotation to remove the low-density graphite. Graphite, referred to as plumbago in the early eras, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. [6] Because it is precipitated, it has a high degree of crystallinity, and that makes it a preferred material for many electrical uses.

Although carbon has been used as coal for thousands of years, Antoine Lavoisier showed us that it was a chemical entity in 1772. It is soft, malleable, ductile, and an excellent conductor of heat and electricity, and it resists corrosion. Graphite is formed by the metamorphosis of sediments containing carbonaceous material, by the reaction of carbon compounds with hydrothermal solutions or magmatic fluids, or possibly by the crystallization of magmatic carbon. 2. Not all diamonds are colorless. Railroads would often mix powdered graphite with waste oil or linseed oil to create a heat-resistant protective coating for the exposed portions of a steam locomotive's boiler, such as the smokebox or lower part of the firebox. Phosphorus is obtained from calcium phosphate by heating the rock in a furnace to yield tetraphosphorus vapor. Diamonds are truly one of natures most fascinating gemstones. However, being exposed to too much carbon dioxide can be dangerous and can cause headaches, pins and needles, difficulty breathing, dizziness, sweating, tiredness, high blood pressure, elevated heart rate, and more.

Crystals of graphite are relatively rare and most often occur in marble. Lithium metal is made by electrolysis of fused lithium chloride. } Pure lithium metal is extremely corrosive and requires special handling. Graphite is a non metal but still can conduct electricity because of the delocalised (free) electrons in its structure. This is because each carbon atom in graphite is bonded to only three other carbon atoms and its fourth valence electron is free. The diamond color depends on the trace elements present or the introduction of other impurities during formation. This creates high electrical conductivity and high thermal conductivity.
