Abstract: The effect of high -melting-point metals W and Mo on the production rate in the preparation of ultrafine Ni and Cu powder using "hydrogen plasma-metal" reaction method is investigated. It is indicated that the production rate has been improved. And the ultrafine powders hardly contain any W and Mo. The causes of high production rate are also discussed.

Key words: Cu, production rate, Ni, ultrafine powders
