Abstract

There are known molded bodies for the safe, long time fixation of radioactive and toxic wastes which have a matrix of graphite and inorganic binding agent, preferably nickel sulfide. An increased resistance to leaching is obtained with molded bodies that have a waste containing nucleus and a waste free shell made of the same graphite matrix.
