Synthesis, anti-migration and burning rate catalytic mechanism of ferrocene-based compounds

One of the most important components of solid rocket propellant is the burning rate catalysts (BRC) which enhance burning rate of solid composite propellant. Low‐pressure exponents and stable burning rate are the key features of an excellent solid propellant. Addition of BRC to the propellant results in the increase of burning rate of the propellant and decrease in pressure exponents. Among all BRC, ferrocene‐based BRC have attracted much attention because of their better microscopic homogeneities in distribution, ignitability of the propellants and good compatibility with organic binder. However, the main barrier for the development and practical applications of ferrocene‐based BRC is their migration property. This article reviews the field and highlights recent progress. Copyright © 2014 John Wiley & Sons, Ltd. Burning rate catalysts (BRC) are important to increase burning rate of the propellant and decrease pressure exponents. Among all BRC, ferrocene‐based burning rate catalysts show good burning rate catalytic activity. In this review, synthesis, anti‐migration and burning rate catalytic mechanism of ferrocene‐based compounds have been compiled and discussed.
