The Use of Graphite Electrodes in Electrolysis

Electrodes are essential as through them the current enters and exits from the solution. Graphite is known to be an excellent conductor which is why graphite electrodes are used in electrolysis. 

The Graphite Structure

The graphite structure is basically a large pool of electrons that are floating absolutely freely between various layers of atoms (here the graphite bonds are formed of three out of the four-electron shells of the carbon atom, whereas the fourth electron moves freely). The electrolysis process can run smoothly because of these electrons that function as a powerful conductor. Moreover, graphite is robust and remains stable at high temperatures. Besides, it is economical as well. All these factors lead to the frequent use of graphite electrodes in electrolysis.

Graphite as an Electrode

The graphite’s atomic structure results in a huge number of electrons that are not being bonded, allowing them to roam between the layers of graphite. The graphite attains its great conductive properties from this large number of free electrons (electron delocalization). Besides being a good conductor, graphite is also sturdier, economical, and easily accessible. All these factors became crucial reasons to use graphite as an electrode.

Graphite Electrodes During Electrolysis

The Graphite helps the positively charged ions which are the metals and hydrogen to attain electrons from the negatively charged electrode. Contrarywise, negatively charged ions lose electrons (oxidation). The wholesale graphite rod manufacturer provides these robust and cost-effective graphite electrodes which have not only great conductive properties but high melting point as well which makes it an excellent choice for electrolysis.
