Effect of Zeta Potential of Stanum Oxide (SnO2) on Electrophoretic Deposition (EPD) on Porous Alumina

Article Preview

Abstract:

Zeta potential analysis of stanum oxide (SnO2) aqueous suspensions (pH7 to pH11) was performed prior to the electrophoretic deposition (EPD) of SnO2. Deposition of SnO2 on porous alumina was obtained by applying the EPD technique carried out by applying voltage of 18V for duration of four minutes. It was found that the depositions SnO2 suspended at pH 7 to pH 11 were successful. The relation between the SnO2 deposition with SnO2 pH and zeta potential values was established in which increased value of pH causes decreased value of zeta potential and decreased SnO2 deposition through EPD technique.
