Aluminum nitride (AlN)
Aluminium nitride is a material of interest in the electronics field due to its excellent thermal conductivity and thermal expansion coefficient matching that of silicon.
Due to the small atomic weights of the two elements that make up the AlN molecule, the relatively simple crystal structure, good simple harmonicity, the formation of Al-N bond lengths are short, the bond energy is large, and the resonance of covalent bonding is conducive to the mechanism of phonon heat transfer, so that the AlN material has excellent thermal conductivity than the general non-metallic materials, in addition to the AlN has a high melting point, high hardness, and high thermal conductivity, and a good dielectric properties.
Aluminium nitride ceramics have been widely used in many civil and military applications due to their excellent performance in various aspects. 5G era, new energy vehicle era, and the advent of the artificial intelligence era will make aluminium nitride ceramics more in demand.
