What is synthetic graphite anode?

2022-07-06 15:30

Description

A synthetic graphite anode is an electrode made of graphite that is used in a mercury cell in order to produce chlorine by electrolysis. As the graphite rod is inserted into a mercury pool cathode of an ignitron, an electrical current begins to flow because it is a collector of electrons in a beam power tube.

What Does synthetic graphite anode Mean?

A synthetic graphite anode is an electrode made of graphite that is used in a mercury cell in order to produce chlorine by electrolysis. As the graphite rod is inserted into a mercury pool cathode of an ignitron, an electrical current begins to flow because it is a collector of electrons in a beam power tube.

synthetic graphite anode material is burned with oxygen to produce CO2, thus making it a combustible material. It has an autoignition temperature of about 700°C (1292°F) and a combustion energy of 33 kJ g−1, although its combustion energy is only fully released when the graphite material has been ejected from the cell and then burned completely outside at high enough temperatures

How is synthetic graphite anode used in cathodic protectionsystems?

A galvanic cathodic protection system consists of sacrificial anodes, made from graphite or other material, connected together to protect a structure. The system's natural potential must be more negative than the structure so that the cathodic protection current moves from the anode (which is more negative) to the structure (which is less negative) when connected in a circuit

Impressed current cathodic protection (ICCP) refers to a method whereby the potential difference between the galvanic/sacrificial anode and the steel structure is not enough by itself to generate a current sufficient to provide protection. In these cases, a power supply is used to generate a larger potential difference, enabling more current flow into the structure being protected.

How to manufacture synthetic graphite anode?

synthetic graphite anode have been commercially available since 1940. They are produced by bonding carbonaceous fillers with carbon-yielding binders, extruding them into rods, and baking them at 1,000°C (1,830°F), which carbonizes the pitch binder. The anode is placed in an electric graphite furnace after cooling and then reheated to over 250°C (480°F), completing the graphitization process. When graphitizing at elevated temperatures, the anode becomes more porous. After this process is completed the material has improved crystalline properties such as electrical and thermal conductivity

Both natural and synthetic graphite are used to produce electrodes for battery technologies.
