Abstract:
A carbonaceous reagent is provided for modifying a carbonaceous binder used in the manufacture of fired carbon articles and carbon-bonded refractories. The reagent serves to increase the carbonization yield of the binder. The reagent contains one or more functional groups each of which has one or more oxygen atom, has an atomic ratio of oxygen to carbon of from 0.05 to 0.30, and a carbonization yield per se of at least 50 percent.
