Abstract
In order to study the sintering kinetics of the ternery system, U-Ce-O, its shrinkage rate with time and temperature at the Ar atmoshpere were measured by using the dilatometer. At the sintering kinetics of U-Ce-O, sintering rate curve revealed bimodal and the first extreme point at bimodal curve was affected by the $UO_2$ the second one was due to the $CeO_2$. The sintering of $(U, Ce)O_2$ was delayed as increasing the $CeO_2$. At the same lOwt. % content, the highest sintering rate was observed at the $(U, Ce)O_2$ sample ball-milled for 4 hours.
3원계 U-Ce-O산화물의 소결거동을 연구하기 위하여 $UO_2$ 및 $CeO_2$분말을 ball-mill 방법으로 혼합한 (U, Ce)$O_2$의 영향이고, 나중에 나타나는 극대점은 $CeO_2$의 영향 때문이다. 또한 $Ceo_{2}$함량이 증가할수록 소결이 지연됨을 알수 있었다. 동일한 10wt. % $CeO_2$함량에서, 4시간동안 ball-milling을 하였을때가 소결속도는 가장 빨랐다.
