WebSep 24, 2024 · Graphite is a good conductor of heat and electricity. What is the electrical conductivity of diamond? Materials with high thermal conductivity are used in heat sinks. Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity. See more Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene.
