Synthetic Graphite Market

High purity graphite electrodes are used to conduct electrical current to melt scrap steel. Synthetic graphite is used in various compositions, including at a purity of 99.99%. In most metallurgical applications, synthetic graphite is preferred to natural graphite, as they are known to handle very high electric currents, due to their high purity and conductivity.
