The reactions of forming (U,Zr)C solid solutions from their elemental components or similarly less stable reactants such as UC{sub 2} are strongly exothermic due to the high stability of these solid solutions. A simple approach of utilizing this heat of formation energy to assist the solid solution reaction process is intimately mix the less stable reactant powders and pressed them into compact; the compact is then heated to the ignition temperature of the reaction.

Description
The reactions of forming (U,Zr)C solid solutions from their elemental components or similarly less stable reactants such as UC{sub 2} are strongly exothermic due to the high stability of these solid solutions. A simple approach of utilizing this heat of formation energy to assist the solid solution reaction process is intimately mix the less stable reactant powders and pressed them into compact; the compact is then heated to the ignition temperature of the reaction. The feasibility of this reaction method to synthesize (U,Zr) solid solutions has been demonstrated in this study. The preliminary results also show that both the initial composition and the heating rate have a significant effect on the nature of the reaction process. As expected the degree of powder mixing was also found to affect the completeness of the reaction.
