The nature and use of graphite?
Property characteristic
Under normal temperature elemental carbon chemical properties are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvent; incineration under different temperature and oxygen reaction, carbon dioxide or carbon monoxide; in the halogen as long as the fluorine can and elemental carbon as a direct response to; in the heating, elemental carbon is easy to be acid oxidation; at high temperature, carbon but also with many metal response generated metal carbides. Carbon is reduced, and the metal can be exercised at high temperature.
Graphite is the crystallization of carbonaceous elements of mineral resources, it is a hexagon crystal lattice layered structure. Each network layer between the interval of 3.40 a carbon atom, the same network layer in a distance of 1.42. Is the six party system, layered with perfect cleavage. The cleavage surface is mainly composed by molecular bonding, weak on the molecular attraction, because of its excellent natural floatability.
Its use includes making pencil cores and lubricants.
