Investigating The Particle Size Distribution Of Synthesized Copper Powder Via Electrodeposition

This paper describes an investigation into the effects of copper concentration, current density, and time of electrolysis on the particle size distribution and morphology of synthesized copper powder via electrodeposition. Characterization of copper powder was performed using Particle Size Analyzer to determine the size distribution, Scanning Electron Microscope to confirm particle size and shape, and X-Ray Diffraction to determine the phase and structure of copper powder. The result shows that copper powder has a single-phase, specifically Cu with purity of 98.42%, face-centred cubic (FCC) crystal lattice, and dendritic structure with cauliflower-like and corn-like shape particles. Electrolysis experiment at a condition of 0.2 A/cm(2) current density and 0.02 M Cu concentration results in the smallest particle size comprising 0.499 mu m at 3 seconds, and the size distribution resembles a normal distribution at 15 minutes.
