Study on the Nanometer-sized Lead Oxide for the Burning Rate Catalysts

To study the effect of nanometer sized lead oxide on the burning property of NEPE propellant, by using FTIR, we studied the efect of burning rate catalysts on the thermal decomposition of HMX. The method of measuring burning rate by target lines at constant pressure was used to characterize the role of nanometer sized lead oxide in NEPE propellant.The IR spectroscopies showed that nanometer sized lead oxide catalysts system can be able to catalyze the decomposition of HMX. The results of the burning rate measurement showed that the nanometer sized lead oxide can play a role in decreasing the pressure exponent of NEPE propellant.
