Abstract: Detonation synthesis method was introduced to prepare nano-cerium dioxide. Nano-cerium oxide was obtained by this novel method and its effect on the thermal decomposition of ammonium perchlorate (AP) was studied. X-ray diffraction and transmission electron microscope were used to characterize as-prepared materials. Results showed that as-prepared cerium dioxide was cubic phase and its morphology was nearly spherical. The mean size of as-prepared cerium dioxide particles was 55 nm. Differential scanning calorimetry (DSC) was used to test the effect of as-prepared nano-cerium dioxide on the thermal decomposition of AP. Kissinger method was introduced to calculate activation energy of different specimens according to DSC data. Results indicated that nano-cerium dioxide synthesized by detonation method had catalytic effect on thermal decomposition of AP and could decrease activation energy of AP/CeO2 mixture.
