摘要：
The single crystal alpha-Al2O3 nano-powder was prepared by combustion chemical deposition. The crystal growth process was observed with TEM and SEM. The optimum technological condition was determined. The results showed that most of alpha-Al2O3 particles were hexagonal columnar and spherical. And a very small amount of particles were rhombohedra. The alpha-Al2O3 nano-powder with well-distribute particle size could be obtained under the conditions of high temperature, low reactant concentration, appropriate detention time and fast cooling.
