Combustion and thermal decomposition of ammonium dinitramide

The effect of organ-metallic compound OME on the combustion and thermal decomposition of ammonium dinitramide (ADN) was investigated by burning rate measurement, DSC and TG. It is shown that OME can increase the burning rate of ADN within the pressure intervals of 1-12 MPa. TG and DSC tests for ADN and ADN+1%OME indicate that the initial decomposition temperature of ADN can be decreased by the addition of OME noticeably. Furthermore the initial decomposition temperature of ADN is subject to the content of OME evidently. Kinetic analysis for DSC and TG data show that the activation energy of thermal decomposition of ADN has been decreased by about 30% by the addition of 1% OME to ADN.
