Anode Slime Gained During Electrolysis Process of Secondary Copper Anodes
The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...
متن کاملCopper deposition onto silicon by galvanic displacement: Effect of Cu complex formation in NH4F solutions
Copper was deposited onto rotating Si substrates by galvanic displacement in 6.0M NH4F to determine the effects of Cu complex formation on deposition rates. Deposition rates decreased with increasing rotation speed, indicating that Cu(I) intermediates, stabilized by NH3, diffuse away from the Cu surface before they reduce to Cu(0). UV–visible spectra of contacting solutions and direct measureme...
متن کاملAtom probe tomography characterization of thin copper layers on aluminum deposited by galvanic displacement.
″Ultrathin″ metallization layers on the order of nanometers in thickness are increasingly used in semiconductor interconnects and other nanostructures. Aqueous deposition methods are attractive methods to produce such layers due to their low cost, but formation of ultrathin layers has proven challenging, particularly on oxide-coated substrates. This work focused on the formation of thin copper ...
متن کاملA copper electrolysis cell model including effects of the ohmic potential loss in the cell
A computational model of a Cu electrolysis cell is presented. The model includes the microscopic mass transfer and electric field effects, as well as the effects of the ohmic loss of potential in the cell bulk electrolyte. A lumped (0D) estimate for the cell ohmic loss is created by utilizing a 3D electric fieldmodel of the cell and the LambertW-function is applied to include the effects of ohm...
متن کاملUnified Synthetic Approach to Silver Nanostructures by Galvanic Displacement Reaction on Copper: From Nanobelts to Nanoshells
We report a unified nontemplate approach to a variety of silver nanostructures, including nanobelts, dendrites, nanodisks, and nanoshells. The growth of these silver nanostructures occurs by galvanic displacement initiated by short-circuited nanobatteries formed between the copper nano/microparticles and protruding silver “seeds” on their surface. The silver nanostructures share analogous struc...
