Abstract
Contact precipitation of silver with a magnesium powder from 0.0025–0.01 M solutions of the system [Ag(CN)2]−-CN− in the hydrodynamic mode was studied. The dependence of the silver cementation rate in the initial stage on the concentration of the [Ag(CN)2]− complex and on the surface area of the cementing agent was examined, and the relationship of the temperature factor with the depolarization of silver reduction on microcathodes and acceleration of magnesium dissolution on microanodes was analyzed.
