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
n.
1796, from German Graphit “black lead,” coined 1789 by German mineralogist Abraham Gottlob Werner (1750-1817) from Greek graphein “write” (see -graphy) + mineral suffix -ite. So called because it was used in pencils. Related: Graphitic.
graphite
(grāf’īt’)
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 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.
