Graphite is a crystalline allotrope of carbon characterized by a layered structure in which carbon atoms are arranged in hexagonal sheets of sp²-hybridized networks, with strong covalent bonds within layers and weak van der Waals forces between them. This anisotropic bonding yields high electrical and thermal conductivity parallel to the layers, lubricity, and cleavage along basal planes. In research contexts, graphite serves as a precursor and reference material for studying two-dimensional materials such as graphene, intercalation compounds, and electrochemical behavior in batteries, and is widely used as an electrode material, neutron moderator, and model system for investigating electronic band structure and defect-mediated properties in carbon-based solids.
Can copper be turned into gold? For centuries, alchemists pursued this dream, unaware that such a transformation requires a nuclear reaction. In contrast, graphite—the material found in pencil tips—and diamond are both composed ...
