Concentration process for Nickel

NiBrite Nickel Plus II - Hill Brothers Chemical Co.

This supplies part of the nickel ions to the solution while the chloride supplies the remainder. When utilizing NICKEL PLUS II as a low concentration process, higher concentrations of nickel chloride are required. A typical low concentration bath utilizes a Nickel Sulfate concentration of 15-24 opg, Nickel Chloride 14-18 opg and Boric Acid 7 opg.
