摘要
Studies on microwave (MW) heating for sintering UO2 pellets were carried out by using MW ovens of 700 and 1000 W. UO2 pellets were sintered to > 95% theoretical density (TD) by MW heating. The total time of sintering is less than an hour compared to several hours required in the case of conventional sintering. Sintered densities were found to increase with increase in compaction pressure as well as the power used for heating. (C) 2000 Elsevier Science B.V. All rights reserved.
