ABSTRACT:
Ceramic pellets, which may have, or not, nuclear fuel materials embedded therein, are formed by first preparing a gel by precipitation of metallic salts from solutions of their compounds at a concentration of at least 10 grams per liter, said solutions being added dropwise to a coagulation bath which contains, for example, ammonium or sodium hydroxide, whereafter the precipitated gel are fired, in one or two stages, to precondition them prior to the compaction to form the final pellets which are subsequently sintered at an appropriate temperature.
