摘要：
Decomposition of Ce(NH4)(2)(NO3)(5)(.)4H(2)O was investigated by means of TG, DTA and EGA methods. In the fast step dehydration occurs with decomposition leading to formation of crystalline Ce-2(NH4)(3)(NO3)(9) and amorphous NH4NO3. NH4NO3 decomposes first with maximum rate at 210 degreesC. Ce-2(NH4)(3)(NO3)(9) begins to decompose at about 220 degreesC. Decomposition is a very fast process and gives O, H2O, NO, O-2, N2O as gaseous products. The solid product of decomposition is CeO2 with great amount of oxygen absorbed inside its structure.
