Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200 W/(m·K), which is five times more than silver, the most thermally conductive metal. Monocrystalline synthetic diamond enriched to 99.9% the isotope C had the highest thermal conductivity of any known solid at room temperature: 3320 W/(m·K), though repo… WebApr 5, 2024 · Pure diamond is the hardest naturally occurring substance known and is a poor conductor of electricity.Graphite, on the other hand, is a soft slippery solid that is a good conductor of both heat and electricity. Carbon as diamond is the most expensive and brilliant of all the natural gemstones and the hardest of the naturally occurring …
