Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss. Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss. It is the thermodynamically most stable allotropic form of carbon. Its color varies from steel grey to black, depending upon the origin, and it has a metallic luster. Graphite is the crystalline allotropic form of carbon that occurs in a free state in nature. It can be prepared artificially by heating a mixture of sand and coke in the electrical furnace at about 3300 K. In Graphite, the carbon atoms are sp2 hybridized. Covalent bonds link each carbon atom. As the photons travel faster through the planes that are narrowly built but move slowly from one plane to the next, the carbon crystal has heavily anisotropic thermal and acoustic features. The uses of the crystal include electrodes and refractories used in applications for processing materials at high temperatures, all due to the single reason that. Graphite has high thermal and electrical conductivity and high thermal stability. Mainly at temperatures of 700 °C and above, the crystal carbon undergoes oxidation to form CO2. In modern times, Graphite is usually consumed in steelmaking, brake linings, lubricants, foundry facings, and batteries, to name a few. One of the important components of Graphite, viz. graphene, has certain special features and is one of the widely known strong materials. Separating the component from the carbon crystal would require better technological advances. The uses of the crystal include electrodes and refractories used in applications for processing materials at high temperatures.
