Transformation of Combustion Nanocatalysts inside Solid
In order to improve the combustion efficiency of solid propellants, one of the most effective ways is to add nano-sized catalysts. It has been shown that the catalysts could largely increase the burn rate and combustion efficiency of the solid propellants by changing the solid-state and gas-phase reaction mechanisms of between the oxidizers and fuels generated by the main ingredients such as binders, RDX, and AP.
