• The formation of PuC<SUB>1-x</SUB> and Pu<SUB>2</SUB>C<SUB>3</SUB> by heating a powdered mixture of PuO<SUB>2</SUB> and graphite was studied in the temperature range of 1, 000°1, 350°C under reduced pres-sure. The reactions were pursued thermogravimetry, X-ray and chemical analyses.<BR>The reaction rates for the formation of PuC<SUB>1-x</SUB> and Pu<SUB>2</SUB>C<SUB>3</SUB> obey the surface reaction law, the apparent activation energies of carburization being 102 and 105 kcal/mol, respectively. In the reaction between PuO<SUB>2</SUB> and graphite, Pu<SUB>2</SUB>C<SUB>3</SUB> is formed directly, and PuC<SUB>1-x</SUB> is formed in turn therefrom. When the carbides are heated continuously above 1, 450°C, appreciable weight loss takes place, which could be attributed to evaporation of Pu from the carbides.
