14 4A Graphite and DiamondStructure and Properties

Graphite has a high melting point similar to that of diamond In order to melt graphite it isn t enough to loosen one sheet from another You have to break the covalent bonding throughout the whole structure It has a soft slippery feel and is used in pencils and as a dry lubricant for things like locks You can think of graphite rather

Graphite Molecular StructureWorld of Molecules
