The distribution of inorganic impurities in graphite electrodes was investigated by means of radiography, ash pattern technique and sulfur print technique. The pattern of the radiograph of an electrode corresponded closely with its ash pattern.
Radiography of graphite electrode was proved to be useful in showing not only the distribution of inorganic impurities in the electrode, but also the texture of the electrode, such as the shape and distribution of both coke grains and pores.
