Thermal conductivity of natural diamond was measured to be about 2200W / (m. k), which is five times more than the silver, the most thermally conductive metal. In case of diamond, each carbon atom is covalently bonded with four other carbon atoms and hence no free electrons are available to conduct electric current. K), which is five times more than silver, the most thermally conductive metal. Although heat conduction and electrical conduction have a correlation because electrons passing by make it easy to conduct heat. So therefore thermal conductivity is directly proportional to electrical conductivity. Diamonds can conduct heat well, as we already said, but they are electrical insulators, meaning that no free particles can manage to go through its dense carbon matrix. What are the fundamental assumptions in Debye's theory of lattice specific heat of solids? Can a diamond conduct electricity? What is structure of graphite? Now unlike most electrical insulators diamond is a good conductor of heat because of strong covalent bonding and low photon scattering. The strong bonds between carbon atoms in a diamond crystal make it good at conducting heat.
