Synthesis of Aluminum Nitride by Nitridation of γ-Al2O3 Nanoparticles in Flowing Ammonia

摘要：

　　Aluminum nitride (AlN) powder was synthesized by gas reduction-nitridation of γ-Al2O3,using NH3 as the reactant gas.The results showed that AlN can be fabricated by this process at 1100℃ for over 480 min in the flowing NH3 atmosphere.However,no AlN was found in the products synthesized at 1300℃ and 1400℃,which was different from the former reports.A series of experiments with different parameters were carried out,and the effects of reacting temperature and time on the synthesis of AlN were investigated.The reaction mechanism was also studied.
