Over a long period of time, in the research of catalysis burning mechanism in double-base propellant, it is well known that many kinds of metal compounds can increase the burning rate of propellant, but only lead compound can make burning rate-pressure curve show super-rate burning, plateau and mesa burning. It is also known that adding a little fine grain of copper compound and carbon black into double-base propellant with lead salt can play a role of assistant catalysis. That is to say, it can gain better catalysis efficiency than lead being used alone and increase burning rate further without destroying the plateau effect (Singh and Rao, 1988; Hewkinet al., 1971; Kubotaet al., 1971 and Cai, 1987).
