Effect of Zeta Potential of Stanum Oxide (SnO<sub>2</sub>) on Electrophoretic Deposition (EPD) on Porous Alumina

Zeta potential analysis of stanum oxide (SnO 2 ) aqueous suspensions (pH7 to pH11) was performed prior to the electrophoretic deposition (EPD) of SnO 2 . Deposition of SnO 2 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 SnO 2 suspended at pH 7 to pH 11 were successful. The relation between the SnO 2 deposition with SnO 2 pH and zeta potential values was established in which increased value of pH causes decreased value of zeta potential and decreased SnO 2 deposition through EPD technique.
