ABSTRACT A short review about ferrocene‐based burning rate catalysts (FBRC) for solid composite propellants is presented. Historically, transition metal oxides (TMO) have been utilized as (BRC) since the start of rocket propellant development. However, these compounds a marked tendency to migrate through grain and crystallize at boundary surfaces. Consequently, FBRC emerged an alternative TMO. After reviewing recent advances in field, we suggest that continued use Catocene [2,2′‐bis(ethylferrocenyl)propane] Butacene liquid BRC choice based on trade‐off between high rates, limited migration from propellant, simpler synthetic pathways, lower costs production comparison with later developments area FBRC. Then, this work aims contribute state art research, highlighting importance Butacene, most field FBRC, particularly regarding their role decreasing decomposition temperature ammonium perchlorate and/or increasing rate.

In order to solve the problems of low effective oxygen content, density and high mechanical sensibility ammonium perchlorate (AP) for propellant, potassium (KP), which has a higher greater was introduced. An AP/KP composite oxidizer prepared using electrostatic spraying. The morphology, structure, thermal properties, safety, combustion performance samples were characterized scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), diffraction (XRD), quadruple coupling technique (TG-DSC-FTIR-MS). Comparative studies performed with raw materials physically mixed samples. results indicate that crystal structures AP KP remained unchanged in oxidizers different methods. spray exhibited significantly improved safety compared samples, friction sensitivity reduced by 36% 16%, respectively. Thermal analysis revealed enhanced high-temperature decomposition KP, peaks 49.15 °C 9.67 °C, Additionally, method activation energy KP's from 448.32 440.62 kJ·mol− 1 222.80–226.11 1. Compared spraying ignition delay time oxidizer, increased aluminum powder rate, enabled complete Al powder. method, its adjustable process parameters controllable sample enhances overall oxidizer.
