  • A gray crystalline allotropic form of carbon which occurs as a mineral in some rocks and can be made from coke. It is used as a solid lubricant, in pencils, and as a moderator in nuclear reactors.

    ‘For instance, carbon may exist as either graphite or diamond in its solid phase.’
    • ‘Carbon, in the forms of charcoal, graphite, and diamond, was one of the earliest elements known to man.’
    • ‘One possibility of this sort of manipulation could turn carbon into either graphite or diamond.’
    • ‘Diamond and graphite both have a variety of important commercial and industrial uses.’
    • ‘It involved passing an electrical discharge between two rods of graphite (which is pure carbon).’
    • ‘Arrows can be made from wood, fibreglass, aluminium and carbon graphite.’
    • ‘Some materials commonly used as unreactive anodes are platinum and graphite.’
    • ‘Erasers made for graphite in black pencils work by adhesion, lifting the mark from the paper.’
    • ‘With the exception of graphite, they are poor conductors of electricity.’
    • ‘The sheet of graphite has rows of conjoined hexagons, separated by horizontally running zig-zag lines.’
    • ‘A scanning tunneling microscope image shows liquid crystal molecules aligned on a sheet of graphite.’
    • ‘The leads are comprised of finely ground graphite and clay, which results in smooth, consistent lay down.’
    • ‘Students were allowed to use graphite pencil or a very fine-tipped felt pen.’
    • ‘A nanotube is essentially a sheet of graphite rolled into a cylinder forming a single molecule.’
    • ‘The sample contains graphite, but no monazite was found in the heavy mineral concentrates.’
    • ‘A diamond is a perfect crystal lattice while the graphite arrangement is more random.’
    • ‘It even resumed operations of an experimental graphite nuclear reactor.’
    • ‘The cesium ions interact with the graphite and eject the carbon ions.’
    • ‘One of the benefits of using graphite is that it keeps the silver from oxidizing, so bullets come out bright and shiny.’
    • ‘Permanent moulds also can be made from either bronze, aluminum, rubber or graphite.’


Late 18th century coined in German (Graphit), from Greek graphein ‘write’ (because of its use as pencil ‘lead’).
