Abstract (en)
[origin: EP0055508A2] Carbon dioxide and air reactivity reactions which occur during carbon electrode use, are reduced by treating the coke used to make the electrode after calcination with water containing a monomeric, dimeric or polymeric-phosphoric acid, or a salt thereof. A representative acid is orthophosphoric acid.
