What Is The Thermal Conductivity Of Aluminium Dodecaboride?

Aluminum dodecaboride (AlB12) is a ceramic material with high thermal conductivity. Its thermal conductivity value varies depending on factors such as temperature, impurities, and crystal orientation.

At room temperature, the thermal conductivity of AlB12 ranges from 160-200 W/mK, which is higher than most metals and ceramics. However, at higher temperatures (>1000°C), the thermal conductivity of AlB12 starts to decrease due to phonon scattering caused by lattice defects and anharmonic vibrations.

The thermal conductivity of AlB12 can also be affected by impurities such as oxygen, carbon, and nitrogen. Impurities tend to scatter phonons and reduce thermal conductivity. Therefore, the presence of impurities in AlB12 can significantly affect its thermal conductivity.

Finally, the crystal orientation of AlB12 can also affect its thermal conductivity. AlB12 has anisotropic thermal conductivity, meaning that its thermal conductivity can vary depending on the direction in which heat flows relative to the crystal structure.

In summary, the thermal conductivity of aluminum dodecaboride can range from 160-200 W/mK at room temperature but can be influenced by factors such as temperature, impurities, and crystal orientation.
