The microstructure of sintered uranium dioxide was studied in relation with several parameters. Especially the sintering temperatures and atmospheres. The external surface and the internal microstructure were examined, using fractography and ceramography. Various techniques for preparing surfaces (mechanical and electrolytic polishing) and for revealing the structure (chemical and anodic attack, ionic bombardment oxidation) were used and compared. Patterns similar to those revealed in metals and probably related with interactions between dislocations and vacancies were observed. (auth)
