Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
The main components of carbon electrodes are graphite, carbon powder and other impurities which are not converted into graphite. The resistivity is higher than that of graphite electrode. These electrodes are mostly used in electric furnace steelmaking, smelting aluminium oxide and other electric arc furnaces.
Graphite electrode should be relatively pure, composed of graphite.
