Natural graphite is mostly used for refractories, batteries, steelmaking, expanded graphite, brake linings, foundry facings, and lubricants. The use of graphite as a refractory (heat-resistant) material began before 1900 with graphite crucibles used to hold molten metal; this is now a minor part of refractories. In the mid-1980s, the carbon-magnesite brick became important, … WebGraphite is amongst the most commonly known and naturally found allotropes of carbon. It is comprised of a layered structure having sp 2 hybridized carbon atoms with one free electron capable of forming coplanar and interplanar bonding. The layers, stacked through secondary bond forces, can slide over one another [14].In other words, graphite …
