To answer this, we must first understand that there are two types of graphite: natural and synthetic. The graphite used to fabricate EDM electrodes, and thus produce machining dust is synthetic graphite and considered to be a biologically inert material and producing dust classified as a nuisance instead of a hazard.

Synthetic and natural graphite electrodes were examined and six different milling energy values were applied to each graphite type. For the first time, ethanol was successfully used as a liquid milling media. Results indicate a clear relationship between a milling energy, an initial capacity, and a cycle life behavior of the electrode.

Synthetic graphite electrodes are made in various grades, like ultra-high power (UHP), high power (HP), and regular power (RP), based on electric current capability. 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%.

Artificial graphite (nongraphitic carbon) is fabricated by heat treatment of petroleum coke, coal-tar pitch, or oil. Specific capacity and reversibility is lost at high temperatures from 1000kg −1 (at 500 °C) to 150kg −1 (1800 °C). Above 2000 °C, an increasing degree of graphitization improves capacity again (200–300kg −1) and minimizes irreversible charge.
