Description
The stepwise isothermal dilatometry (SID) is extended to study the shrinkage kinetics at the intermediate stage of sintering. Based on Coble's model and the linear dependence of the cube of the grain diameter on time; an equation describing the intermediate stage of sintering, has been derived as function of shrinkage and shrinkage rate. The intermediate stage shrinkage kinetics of U O2 compacts - sintered in H2 and H2+10% CO2 and Ce O2 compacts sintered in oxygen, have been studied. reasonable values of activation energies of 516.2 ± 46, 438.9 ± 35, 422 ± 34, kJ/mole have been obtained, respectively. These satisfactory results reveals the validity of this technique in studying the intermediate stage of sintering. 7 figs
