Aluminium nitride is a covalently bonded metal nitride, and possesses a hexagonal crystal structure. It is manufactured by the carbo-thermal reduction of aluminium oxide in the presence of gaseous ammonia or nitrogen or by straight nitridation of aluminium. Aluminium nitride is popular in end use industries due to its beneficial properties, such as high thermal conductivity, high electric insulation, and high mechanical strength. It exhibits high thermal conductivity that is nine times that of alumina. Along with that, aluminium nitride possesses a coefficient of thermal expansion close to that of silicon, which helps it in achieving high reliability in Si chips and thermal heat cycling in end use applications. In terms of purity, aluminium nitrides possess high purity and negligible toxicity, as compared to other metal nitrides.
Aluminium nitride is a fascinating material and is one of the finer options for use in products requiring high thermal conductivity. This, along with exceptional electrical insulation characteristics, make aluminium nitride an exceptional heat sink material for numerous electrical, as well as electronic applications and uses. Aluminium nitride components are stable at high temperatures; in inert conditions and in air, oxidation occurs at above 700 °C. Aluminium nitride is stable in carbon dioxide and hydrogen atmospheres up to 980 °C. On the basis of stability of metal nitrides, aluminium nitride is relatively more stable against molten salts, including cryolite, carbonates, chlorides, and eutectic mixtures. On the basis of corrosion, acids attack the secondary phase of aluminium nitride, whereas strong alkalis dissolve aluminium nitride’s base material. In recent years, conventional metallizing processes have been developed, which have been used for high volume production across the globe. This conventional process is expected to produce maximum yield and hence, will help increase profits on the manufacturer side.
