Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. … See more Natural graphite The principal types of natural graphite, each occurring in different types of ore deposits, are • Crystalline small flakes of graphite (or flake graphite) … See more In the 4th millennium BCE, during the Neolithic Age in southeastern Europe, the Marița culture used graphite in a ceramic paint for decorating pottery. Sometime before 1565 (some sources say as early as 1500), an enormous deposit of graphite was … See more Invention of a process to produce synthetic graphite In 1893, Charles Street of Le Carbone discovered a process for making artificial graphite. In the mid … See more The most common way of recycling graphite occurs when synthetic graphite electrodes are either manufactured and pieces are cut off or lathe turnings are discarded for reuse, or the electrode (or other materials) are used all the way down to the electrode … See more Graphite occurs in metamorphic rocks as a result of the reduction of sedimentary carbon compounds during metamorphism. It also occurs in igneous rocks and in meteorites. Minerals … See more Natural graphite is mostly used for refractories, batteries, steelmaking, expanded graphite, brake linings, foundry facings, and lubricants. Refractories See more Graphite is mined by both open pit and underground methods. Graphite usually needs beneficiation. This may be carried out by hand-picking the pieces of gangue (rock) and hand … See more WebAlthough graphite is considered an inorganic material, its “roots” are firmly in organic chemistry – or loosely speaking - the study of carbon compounds. This definition can be further refined to include only carbon compounds derived from “organic” materials such as plants, animals, etc.
