graphite(redirected from Natural graphite)
Also found in: Thesaurus, Medical, Encyclopedia.
A soft crystalline allotrope of carbon, composed of graphene layers, having a steel-gray to black metallic luster and a greasy feel, used in lead pencils, lubricants, paints and coatings, and fabricated into a variety of forms such as molds, bricks, electrodes, crucibles, and rocket nozzles. Also called black lead, plumbago.
gra·phit′ic (gră-fĭt′ĭk) adj.
(Elements & Compounds) a blackish soft allotropic form of carbon in hexagonal crystalline form: used in pencils, crucibles, and electrodes, as a lubricant, as a moderator in nuclear reactors, and, in a carbon fibre form, as a tough lightweight material for sporting equipment. Also called: plumbago
[C18: from German Graphit; from Greek graphein to write + -ite1]
a soft native carbon occurring in black to dark gray foliated masses: used for pencil leads, as a lubricant, as a moderator in nuclear reactors, and for making crucibles and other refractories; plumbago.
[1790–1800; < German Graphit < Greek gráph(ein) to write, draw + German -it -ite1]
gra•phit•ic (grəˈfɪt ɪk) adj.
A naturally occurring, steel-gray to black, crystalline form of carbon. The carbon atoms in graphite are strongly bonded together in sheets. Because the bonds between the sheets are weak, other atoms can easily fit between them, causing the graphite to be soft and slippery to the touch. Graphite is used in pencils and paints and as a lubricant and electrode. It is also used to control chain reactions in nuclear reactors because of its ability to absorb neutrons. See Note at carbon.
