The Carbon and Graphite anode - …

2017-3-13 · Bulygin 178 has studied the density distribution in the surface layer of a graphite anode at high and low C.D.'s. At high C.D. the electrolysis process was found to occur in only a small number of large pores resulting, after a time (4 hours in Buly-gin's case) in abrupt crumbling of the surface layer.

Anode - Sacrificial Positive Electrode

In electrolysis, an electrode connected to the charger's positive terminal is called anode. The anode is also called "sacrificial" or "waste" electrode because it can be expected to disintegrate and visibly decrease in size during the process. The choice of a conductive object to be used as an anode in electrolysis should be considered carefully.
