摘 要：<正>The nanosize AlN particles wereprepared by evaporation-condensation method in DCarc nitrogen plasma. Aluminium of high purity（99. 999% ） was evaporated and nitrided in nitro-gen plasma by use of high temperature and high re-activity of plasma gas. The purity of nanosize AlNparticles is more than 98% （wt%） and the averageparticle size is about 50nm. The grain growth ofnanosize AlN particle is also studied. The resultsshow that the nanosize AlN particle begins to growup at 900℃ and the grain growth increase rapidlyat 1100℃. When the temperature is increased to1600℃, the surface of nanosize AlN particle hasbeen sintered softly. Results will be beneficial to prepare AlN ceramics.
