摘要
The effect of lead carbonate (PbCO3) on the combustion characteristics and thermal decomposition behavior of ammonium dinitramide (ADN) is investigated by burning rate measurement, DSC and TG techniques. Results show that the burning rate of ADN + 5% PbCO3+0.2% paraffin system is higher than that of ADN + 0.2% paraffin system in the pressure range of 3-12 MPa, and PbCO3 enables mesa combustion effect of ADN + 0.2% paraffin system to disappear. TG and DSC curves of ADN and ADN + 5% PbCO3 system indicate that the initial decomposition temperature of ADN can be decreased by the addition of PbCO3. Kinetic analysis for DSC data show that the apparent activation energy of thermal decomposition of ADN decreases when 5% PbCO3 is added into ADN. Moreover, both combustion characteristics and surface-melting layers of ADN mixtures are considered to be correlative.
