Can inert electrodes be made of carbon

WebPreferably, the electrode is an anode and the anode body has a bore shape with a continuous external surface of the body wall. Preferably, the electrode body is made from a metal alloy, a ceramic or cermet material to form an inert or oxygen-evolving anode used for an eco-friendly production of aluminum. WebCarbon paste electrodes are also useful in many applications. These electrodes are made from a paste of finely granulated carbon mixed with an oil substrate like Nujol. The paste is then packed into a cavity in an inert electrode body. Carbon paste electrodes have the disadvantage of being prone to mechanical damage during use.
