抄録

Nickel ultrafine particles were produced using the Ar-H2 arc plasma method under constant electric power. The factors which affect the ultrafine particle generation process were chosen as the hydrogen content in a mixed gas and the electrode angle. The generation rate of ultrafine particles depends on the electrode angle. The mean diameter of ultrafine particles converted from a specific surface area increases with increasing hydrogen content and electrode angle. In order to explain these phenomena, a new idea was proposed on the basis of a mass transport in the arc plasma.
