研究了在高氮/低氧混合气氛下热处理（500～700℃）对AlN（氮化铝）粉体表面特性及粉体抗水解性能的影响。实验结果表明：在高氮/低氧混合气氛保护下的AlN粉末表面覆盖了氧化铝薄膜层结构，有效地抑制了AlN与水的反应，阻碍了水分子向 AlN 粉末表面侵蚀的作用，提高了AlN粉末在潮湿环境中的抗水化能力，且热处理后粉末在水溶液中高剪切应力球磨过程中具有非常好的稳定性。

Aluminum nitride ( AlN) powder was heated at 500~700℃ in protective gas mixed with high nitrogen and low oxygen,in order to investigate the effect of heat treatment on AlN powder?s surface properties and hydration resistance.The results show that the surface of AlN powder was coated by a structure of oxidation product,which is favor to form a diffusion barrier between water and AlN surface,thus restrain hydrolysis reaction and increases the water-resistance of AlN powder in wet environment. After heat treatment,the AlN powder kept high stability of hy-dration resistance in aqueous ball milling at a high cutting stress.
