How Does The Conductivity Of Aluminium Diboride Compare To Other Materials?

Aluminium diboride (AlB2) is a ceramic material that exhibits high thermal conductivity and moderate electrical conductivity. Compared to other materials, such as metals like copper and silver that are highly conductive, aluminium diboride's electrical conductivity is relatively low. However, it has higher conductivity than most other ceramics.

The electrical conductivity of aluminium diboride depends on several factors, including the purity of the material, its crystal structure, and the presence of impurities or defects. Generally, pure AlB2 samples have a conductivity in the range of 1-50 S/cm, which is lower than that of metals but higher than most other ceramics.

On the other hand, the thermal conductivity of aluminium diboride is quite high, surpassing most metals and ceramics. This property makes it an attractive material for applications in high-temperature environments, where efficient heat transfer is essential.

In summary, while aluminium diboride has moderate electrical conductivity compared to metals, it exhibits high thermal conductivity that exceeds that of most materials.
