Production of the Zinc Powder from Zinc Oxide with Sodium Hydroxide Solution by Electro Deposition

Abstract

In study of the effect of deposition time and voltage in production of zinc powder by using electrochemical cell with zinc electrodes having purity of (97.4%) in electrolytic solution consisting mainly of zinc oxide (ZnO) and Sodium hydroxide (NaOH). the parameters affecting the electro deposition production of zinc powder .The physical test were done on the powder, such as particles shape, purity powder, particle size and size distribution. The results showed that variation in voltage, the weight of zinc powder increased with the increase of voltage and particles size decreased with the increase of voltage. While the results showed that variation in deposition time, the weight of zinc powder increased with the increase of deposition time and particles size of zinc powder increased with the increase of deposition time. The result of electro deposition process showed layers deposition for zinc powder on cathode electrode, and forming shape dendritic particles.
