As well as being an excellent conductor, there are several other reasons why graphite is a common choice for electrodes. Graphite has a very high melting point, enabling it to be used to conduct electricity in high temperature reactions without changing state. With such a high degree of stability, graphite can be used when other materials would be unsuitable. Another explanation to answer the question, “why is graphite used in electrodes?” relates to its relative cost and prevalence. Graphite can be created synthetically and there are also extensive deposits which are mined worldwide. As an easily obtainable material that has the properties necessary for electrodes, graphite is therefore a cost-effective, convenient option, providing another reason why graphite is used to make electrodes.

Did you know that there are two ways to make iron? The blast furnace method and the electric arc furnace method. The electric arc furnace method recycles used iron scrap by melting it in an electric arc furnace. It is the graphite electrodes inside the furnace that actually melt the iron. Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron. In recent years, graphite electrodes have been made even more efficient: they can now conduct even higher currents and more power. Using the expertise collected over a century of innovation, Tokai Carbon has developed the world's biggest electrodes. They measure 32 inches (about 80 cm) in diameter and are 3 meters long. Tokai Carbon's graphite electrodes are made to last, making them a trusted name in the industry.
