Abstract: By using the measurements and calculations of burning rate, burning heat, activation energy and distribution of temperature, it is found that Fullerene can obviously raise the propellant’s flame temperature and surface burning temperature, reduce the pressure index. The range of plateau effect for propellants containing Fullerene is extended and moves towards high pressure direction. its burning heat is also raised about 10%. lt can be Pointed from the reaction mechanism that Fullerene and lead form the complex C(60)-Pbx which has catalysis action and improves the combustion characteristic of double-base proPe1lants. Because C,, in the soots which contain 10% C6, mainly exists in molecular state and is uniformly dispersed into propellant, the chemical activities of C,, can bepreserved, and the soots have better catalytic effect than pure C60.
