Activated Carbon – Baking


Baking: The process in which the carbonaceous binder, usually coal tar pitch or petroleum pitch, as part of a shaped carbon mix is converted to carbon yielding a rigid carbon body by the slow application of heat. The process can take as short as 14 days in coarse-grained, electrothermic grades (low binder level) and as long as 36 days in ultrafine-grained, specialty grades (high binder level). Depending on the grade, the final baking temperature can be in the range of 1100 K – 1500 K.
