摘要：

Uranium dioxide becomes hypostoichiometric when hated above 1600°C or in a reducing atmosphere. Upon cooling, free metallic uranium is rejected. The role and the effect of rare‐earth oxide additives on the stabilization of urania at high temperatures in a hydrogen environment are evaluated. A tentative phase diagram for the system uraniagadolinia is proposed. Copyright © 1969, Wiley Blackwell. All rights reserved
