Polarization characteristics for electroless gold plating baths consisting of hydrazinium sulfate and sodium gold sulfite were investigated. Both anodic oxidation of a reducing agent and cathode reaction of gold ion were promoted by the bath temperature rise. Mixedpotential theory was materialized in this bath. And rise in bath temperature increased not only reduction rate but also substitution rate.
