저압 Ar 개스중 증발법에 의한 Al 초미분의 크기특성 = Size Distribution of Aluminum Ultra Fine Powder Generated by Evaporation into Low Pressure Argon Environment

다국어 초록 (Multilingual Abstract)

Size distribution of Al ultra fine particles (UFP) generated by evaporating Al vapor into low pressure Ar environment is studied with varied gas pressure, evaporation temperature, position of particle collection, and inert gas velocity. Particles are observed to be spherical irrespective of operating conditions, which shows that they are formed by homogeneous nucleation process and the size distribution is very close to log -nomal. The mean size increases with increased pressure, temperature and the distance to collection and reduced gas whereas the standard deviation decreases with increased gas velocity and temperature.
