• Several rare earth metal oxide dispersions in UO<SUB>2</SUB>-Eu<SUB>2</SUB>O<SUB>3</SUB>, Dy<SUB>2</SUB>O<SUB>3</SUB> and Sm<SUB>2</SUB>O<SUB>3</SUB> were subjected to steep temperature gradient at near melting temperature of UO<SUB>2</SUB> to investigate the compatibility of rare earth metal oxides with UO<SUB>2</SUB>.<BR>The principal results obtained are as follows :<BR>(1) Grains of massive form having a directional growth tendency were formed in the central region of the UO<SUB>2</SUB> containing the dispersions of rare earth metal oxides. No signs of columnar grain growth were observed, such as have been reported in UO<SUB>2</SUB> free of added elements.<BR>(2) The original shapes of all three rare earth metal oxide particles were lost in the massive grain region.<BR>(3) Various particular characteristics were observed in the microstructure of the different rare earth metal oxide-UO<SUB>2</SUB> systems.
