Specific applications and features of graphite electrodes
Graphite Electrodes are used in specific applications where a high level of technical requirement is required for these materials; they can be supplied in sheets, plates, bars, etc. Or to be used in fuel cells, electrolysis, cathode protection, among others.
- Anodization is used to protect metals from corrosion.
- Production of aluminum, lithium, sodium, potassium and magnesium
- Production of sodium hydroxide, sodium chlorate and potassium chlorate.
- Production of hydrogen with multiple uses in the industry: as fuel, in welding, etc.
- The electrolysis of a saline solution allows the production of hypochlorite (chlorine): this method is used to achieve ecological chlorination of pool water.
- Electrometallurgy is a process to separate pure metal from compounds using electrolysis. For example, sodium hydroxide is separated into pure sodium, pure oxygen and water.
- Electroplating, also used to prevent metal corrosion, creates a thin film of a less corrosive metal on another metal.
Features of Graphite Electrodes:
- High performance and high conductivity electrode.
- Longer life than most metal electrodes, due to its minimal corrosion degradation.
- It has a good behavior against chemical corrosion typical of grounding systems (reduction- oxidation reaction, reduction oxide or redox reaction).
- High improvement of the electrical contact properties between the graphite electrode and the ground by graphite powder and conductive salts, making the cracks in the ground around said electrode firm.

- This provides very low impedance at very high frequency compared to conventional ground electrodes used at 50 Hz, which makes it extremely appropriate for dissipating lightning currents.
