发明名称 Method for producing nickel metal powder
摘要 A method for producing nickel powder of controlled geometry useful for conductive or resistive pastes or inks. A nickel salt is precipitated by means of hydrazine, an alkali metal base is added to the precipitate, and the resulting mixture is heated under ambient pressure until nickel powder is precipitated. The geometry such as powder surface area, particle size, and particle shape of the nickel powder end product is controlled by means of the added amount of alkali metal base or added amount of hydrazine and in some instances by means of the temperature.
