Graphitenoun
An allotrope of carbon, consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely, that is used as a dry lubricant and in "lead" pencils.
Graphitenoun
Short for graphite-reinforced plastic, a composite plastic made with graphite fibers noted for light weight strength and stiffness.
Graphitenoun
A grey colour.
Graphitenoun
Native carbon in hexagonal crystals, also foliated or granular massive, of black color and metallic luster, and so soft as to leave a trace on paper. It is used for pencils (improperly called lead pencils), for crucibles, and as a lubricator, etc. Often called plumbago or black lead.
Graphitenoun
used as a lubricant and as a moderator in nuclear reactors
Graphite
Graphite (), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions.
Carbonnoun
(uncountable) The chemical element (symbol C) with an atomic number of 6.
Carbonnoun
(countable) An atom of this element, in reference to a molecule containing it.
Carbonnoun
A sheet of carbon paper.
Carbonnoun
A carbon copy.
Carbonnoun
A fossil fuel that is made of impure carbon such as coal or charcoal.
Carbonnoun
Carbon dioxide, in the context of global warming and climate change.
Carbonnoun
A carbon rod or pencil used in an arc lamp.
Carbonnoun
A plate or piece of carbon used as one of the elements of a voltaic battery.
Carbonverb
To cause (someone) to receive a carbon copy of an email message.
Carbonnoun
An elementary substance, not metallic in its nature, which is present in all organic compounds. Atomic weight 11.97. Symbol C. it is combustible, and forms the base of lampblack and charcoal, and enters largely into mineral coals. In its pure crystallized state it constitutes the diamond, the hardest of known substances, occuring in monometric crystals like the octahedron, etc. Another modification is graphite, or blacklead, and in this it is soft, and occurs in hexagonal prisms or tables. When united with oxygen it forms carbon dioxide, commonly called carbonic acid, or carbonic oxide, according to the proportions of the oxygen; when united with hydrogen, it forms various compounds called hydrocarbons. Compare Diamond, and Graphite.
Carbonnoun
A carbon rod or pencil used in an arc lamp; also, a plate or piece of carbon used as one of the elements of a voltaic battery.
Carbonnoun
a sheet of carbon paper.
Carbonnoun
a carbon copy.
Carbonnoun
an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds
Carbonnoun
a thin paper coated on one side with a dark waxy substance (often containing carbon); used to transfer characters from the original to an under sheet of paper
Carbonnoun
a copy made with carbon paper
Carbonnoun
the chemical element of atomic number 6, a non-metal which has two main forms (diamond and graphite) and which also occurs in impure form in charcoal, soot, and coal.
Carbonnoun
carbon fibre
Carbonnoun
a rod of carbon in an arc lamp.
Carbonnoun
a piece of carbon paper or a carbon copy.
Carbonnoun
carbon dioxide or other gaseous carbon compounds released into the atmosphere, associated with climate change
Carbon
Carbon (from Latin: carbo ) is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.
