Abstract :
Nano iron oxide (α-Fe2O3) exhibits better performance as a burn rate catalyst in composite rocket propellant. A polymer citrate precursor method (a combustion process) was developed (in this laboratory) for large scale synthesis of nanoα-Fe2O3 from starting material iron nitrate. The synthesized nanoα-Fe2O3 wascharacterized for bulk density, powder XRD, BET surface area and HRTEM. Two redox titration methods viz. permanganate and iodometricwere discussed for chemical analysis (assay) of samples. Preliminary study indicates that use of nanoFe2O3in composite propellant formulations resulted in ~ 50% improvement in burn rate.
