Abstract
PURPOSE: To prepare the ultrafine particle in good reproducibility having a narrow particle size range and uniform croystal prperty by appropriately moving the heating part of an evaporation source.
CONSTITUTION: In preparing the ultrafine particle by evaporating a material in an inert gas atmosphere, the heating part of an evaporation source such as a tungsten filament 18 or the like is moved on a support column 14 through a filament support plate 16 corresponding to the temp. of the evaporation source or an evaporation amount. By this mechanism, distributions of a vapor supersaturation degree and a vapor temp. are enabled to be approached to a constant condition and the metal ultrafine particle with a narrow particle size range and crystal property can be prepared.
