    Nickel Powders from the Carbonyl Process

     · The nickel carbonyl gas process fulfils these needs. The Nickel Carbonyl Process. Nickel powders can be made by a number of different processes, including atomisation from melts or precipitation from solutions. However, these techniques tend to give relatively large particles and can be difficult to control economically at fine particle sizes.
