Abstract

Characteristics of the gold deposit produced by the substrate (Ni)-catalyzed process in the thiosulfate-sulfite bath described in Part I of this series of papers are profoundly affected by bath composition and the composition and pretreatment of the substrate. This paper, Part II of a series of two, describes effects of those variables on the appearance, uniformity, morphology, and porosity of the gold deposit.
