 Production Method of Aluminum Nitride (AlN) Powder

Carbothermal Reduction and Nitridation Method

Alumina (Al2​O3​) is mixed with carbon powder. This mixture is heated to 1600 – 1800°C in a nitrogen atmosphere. The carbon reduces the alumina, and the nitrogen reacts with the resulting aluminum species to form AlN powder. The primary reaction can be written as Al2​O3​+3C+N2​→2AlN+3CO.

Chemical Vapor Deposition (CVD)

Gaseous precursors like trimethylaluminum (TMA, Al(CH3​)3​) and ammonia (NH3​) are introduced into a reaction chamber. At temperatures around 1000 – 1200°C, they react. The chemical reaction leads to the deposition of AlN powder. The reaction mechanism involves the decomposition of TMA and the response of aluminum radicals with ammonia-derived nitrogen, e.g., Al(CH3​)3​+NH3​→AlN+3CH4​.

Sol-Gel Method

Aluminum alkoxides and nitrogen-containing compounds are dissolved in a solvent. Through hydrolysis and condensation reactions, a gel is formed. The gel is then dried and calcined at 800 – 1200°C in a nitrogen-rich atmosphere. This process results in the formation of AlN powder.
