Method preparing superfine metallic nickel powder with high frequency plasma

The invention relates to a method preparing spherical metallic nickel powder with high frequency plasma. The method takes the hydrate of metallic nickel or subcarbonate as raw material and carries out hydrogen reduction through the high frequency plasma technology to prepare the superfine spherical nickel powder. Plasma arc is added to the raw material. The plasma is heated in high temperature through high frequency induction and generates reduction reaction with high-activity hydrogen plasma. The superfine spherical nickel powder can be obtained through a shape controller in the condensation process. The utility model is characterized in that the nickel hydroxide or the subcarbonate are used as the raw material, in the reduction process of the plasma, the particle size and the shape of the nickel powder can be controlled easily, the process flow is short and the production process is environment-friendly.
