【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.更多还原
