Abstract
The effect of suspended Si particles on Fe deposition from a FeCl2 solution was investigated. The conductivity of a FeCl2 solution in the presence of suspended Si particles was found to be consistent with the Bruggeman theory and its viscosity shows Newtonian behaviour. The Fe3+ mass transfer to a rotating disc electrode in the presence of Si particles increases with Si content in the solution at higher rotation speeds. The cathodic polarization curves shift to slightly lower potentials and the Fe deposition current efficiency increases with increasing Si concentration. These changes are related to an increase in the rate of Fe deposition on Fe with Si particle content in the solution. Finally, Si embedment in the Fe increases with current density between 0.25 and 2kA m-2.
