• An attempt has been made to pursue the course of the thermal decomposition of uranyl nitrate hexahydrate in the presence of graphite, and compositions of the product at various stages in the decomposition have been determined by X-ray diffraction and by thermogravimetric measurement. The influence of graphite on the decomposition appeared in the temperature region above 500 ??, and reduction with graphite of the decomposed product into uranium dioxide was observed above 750 ?? . It was also demonstrated that uranium dioxide and carbide-dispersed graphite-base fuel could be prepared by thermal decomposition of hexahydrate in the graphite matrix.
