| Abstract: | The sintering kinetics of non-stoichiometric uranium dioxide powders have been studied in the temperature range 700 to 950° C. The results of the relative linear shrinkage during the stepwise heating of samples, were analysed as a function of sintering temperature and time. It has been shown that it is impossible to explain the exceptionally large shrinkage of UO2+x
compacts in the temperature range 0.3 to 0.4 T
m by means of a single sintering mechanism. |
