As a material science expert with a keen interest in the properties of various substances, I am often asked about the thermal conductivity of diamonds. Diamond, a crystalline form of carbon, is renowned for its exceptional hardness and optical properties. However, its thermal conductivity is also a topic of interest, especially in the fields of electronics and engineering where heat management is critical.
Thermal Conductivity is a measure of a material's ability to conduct heat. Materials with high thermal conductivity are desirable in applications where heat dissipation is necessary. Unlike most electrical insulators, diamonds are indeed good conductors of heat. This is primarily due to the strong covalent bonding between carbon atoms in the diamond lattice, which facilitates the transfer of thermal energy through the crystal structure.
The strong covalent bonding in diamonds results in a highly ordered crystal lattice. This order allows for efficient energy transfer through a process known as phonon conduction. Phonons, which are quasi-particles representing the collective vibrations of atoms in a solid, carry heat through the lattice. In diamonds, the low rate of phonon scattering, which is the disruption of phonon movement due to defects or impurities, contributes to its high thermal conductivity.
The thermal conductivity of natural diamond has been measured to be approximately 2200 W/(m·K). This value is significantly higher than that of many other materials, including metals known for their thermal conductivity. For comparison, copper, a common conductor of heat, has a thermal conductivity of about 400 W/(m·K). This means that diamond is roughly five times more effective at conducting heat than copper.
However, it is important to note that the thermal conductivity of diamonds can vary depending on factors such as purity, crystal orientation, and the presence of impurities or defects. Synthetic diamonds, which are often used in industrial applications due to their controlled production process, may exhibit slightly different thermal properties compared to natural diamonds.
In summary, diamonds are excellent conductors of heat due to their strong covalent bonds and low phonon scattering within their crystal lattice. This property makes them valuable in applications where efficient heat transfer is required, such as in high-performance electronic devices and thermal management systems.

Thermal conductivity. 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 copper.
