  • Electrolytic Process an overview ScienceDirect Topics

    Electrolytic processes are used for the production of chlorine and caustic soda [D. Pletcher et al., 1990], or hydrogen and oxygen, or special organic compounds [T. Sata, 1991].The principle of the chlorine/alkaline process is illustrated in the schematic drawing of Figure 1.7 which shows the electrolytic production of sodium hydroxide and chlorine.

  • Electrolytic process Wikipedia

    An electrolytic process is the use of electrolysis industrially to refine metals or compounds at a high purity and low cost. Some examples are the Hall-Héroult process used for aluminium, or the production of hydrogen from water.Electrolysis is usually done in bulk using hundreds of sheets of metal connected to an electric power source. In the production of copper, these pure sheets of copper

  • A Pulse/Pulse Reverse Electrolytic Approach to

    Sep 26, 2011· We developed an electrolytic process for both bulk material removal and electropolishing, based on pulse/pulse reverse waveforms in an aqueous sodium chloride-sodium nitrate electrolyte. We used the same machining cell (Fig. 9) used for the conventional electropolishing process with electrolyte entry/exit through the internal elbow-shaped passages.

    May 15, 2015· This paper reviews the present understanding of electrolytic plasma processes (EPPs) and approaches to their modelling. Based on the EPP type, characteristics and classification, it presents a generalised phenomenological model as the most appropriate one from the process diagnostics and control point of view.

  • Electrolyte Wikipedia

    An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water.The dissolved electrolyte separates into cations and anions, which disperse uniformly through the solvent.Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has

  • Electrolytic Etching. Ethical Making Resource

    Electrolytic etching is a surprisingly old process, dating from the middle of the 19th entury (1840), when a patent was filed for Engraving Metals by Voltaic Electricity _1. The process described in this patent is largely the same as the process detailed below.

  • Electrochemistry Encyclopedia -- Metal powder production

    the process is usually limited to the production of pure metal (non-alloyed) powders. Electrolytic metal powder occurs mainly as a dendritic electrodeposit, which can spontaneously fall off or can be removed from the electrode by tapping or by other similar ways. (Also, the powder has a tendency to form flakes or needles, fibrous or spongy

  • Electroetching Wikipedia

    Electroetching is a metal etching process that involves the use of a solution of an electrolyte, an anode, and a cathode.The metal piece to be etched is connected to the positive pole of a source of direct electric current.A piece of the same metal is connected to the negative pole of the direct current source and is called the cathode. In order to reduce unwanted electrochemical effects, the
