IMPREGNATION OF CARBON REFRACTORY MATERIALS BY CARBONACEOUS AGENTS

摘要

The technique of vacuum pressure impregnation was used to impregnate carbon containing alumina refractory materials for metallurgy. The opportunity to replace coal tar pitches - the most current impregnating agent - by other BaP-free carbonaceous agents is discussed as well as various experimental techniques being suitable to characterize the impregnation.
