Graphite industry

 

Coal tar pitch is used in the production of graphite electrodes (used in steel production) as a binder, and impregnating agent, increasing electrode density and strength. After the aluminium industry, the second largest consumer of coal tar pitch is graphite electrodes (which are used in electric arc furnaces). CTP constitutes around 40-42 percent of a graphite electrode by volume, with a large part of the balance being accounted for by needle coke/CPC (calcinised petroleum coke). CTP is used as a binder and impregnating material in electrodes at a high temperature to fill and cover pores, enhancing electrode life.
