STUDY ON THE FABRICATION OF THE BeO-UO$sub 2$ SINTERED BODY BY MEANS OF VACUUM HOT PRESSING (in Japanese)

Journal Article · · J. Atomic Energy Soc. Japan
OSTI ID:4015002

BeO--UO/sub 2/ sintered bodies containing 2 to 10 wt% UO/sub 2/ were prepared in a graphite mold by hot pressing and induction heating for 60 min at 1,400 to 1,600 deg C under a compression of 160 kg/cm/sup 2/ in a vacuum of 10-/ sup 3/ mm Hg. Under the optimum pressing condition, bodies having the following properties are obtained: density up to 98% of theoretical; bending strength 1,900 to 2,300 kg/cm/sup 2/; thermal conductivity slightly decreased with UO/sub 2/ content down to 0.48 (at 10 wt% UO/sub 2/) cal/cm. sec. deg C at room temperature; linear expansion the same as BeO sintered bodies.
