Contribution to the Study of the Sintering of Uranium Oxide-Technical Applications; CONTRIBUTION A L'ETUDE DU FRITTAGE DE L'OXYDE D'URANIUM

Technical Report ·
OSTI ID:4286960

An investigation was made on the preparation of uranium oxide powders beginning with uranium peroxide and the examination of the behavior of these powders during sintering in a hydrogen atmosphere. The modifications of structure and granulometry which accompany the preparation of uranium oxide powders were studied, and a method of preparation of a powder suitable for sintering at 95% of the theoretical density in hydrogen at temperatures from 1200 to 1400 deg C is described. The determinant factor in assuring the success of sintering is the choice of the primary material whose surface must not be less than 8 to 10 m/sup 2//g. (J.S.R.)
