Application of thermal analysis methods in the study of sintered uranium dioxide preparation. II

It was shown using uranyl gel leached in different time intervals and dried by three different techniques that leaching and dryness significantly affected not only the physical and chemical properties of resulting xerogels but also its calcination during heating to 800 degC in the presence of air. Differences in the course of decomposition of the individual types of materials made it to possible consider a number of processes during decomposition as well as the effect of initial material structure. The respective thermal analysis methods, viz., thermogravimetry, differential and emanation thermal analyses were found to be complementary in the study and interpretation of the above processes.
