Large scale synthesis and characterization of &#x03B1;-Fe<inf>2</inf>O<inf>3</inf> nanoparticles for propellant applications

Abstract

Nano iron oxide (a-FeZ03) exhibits better scale, and consume less energy. Since the large volumes of performance as a burn rate catalyst in composite rocket gases are evolved during combustion of citrate polymer gel it propellant. A polymer citrate precursor method (a combustion limits particle contact and hence, coarsening and process) was developed (in this laboratory) for large scale agglomeration of particles. Moreover, this process produces synthesis of nanoa-FeZ03 from starting material iron nitrate. The high purity powder which is free from chlorine or any other synthesized nanoa-FeZ03 wascharacterized for bulk density, powder XRD, BET surface area and HRTEM. Two redox impurities. The current paper describes the synthesis of nano titration methods viz. permanganate and iodometricwere iron oxide (a-Fe20 3 )in large scale for application in propellant discussed for chemical analysis (assay) of samples. Preliminary formulations. study indicates that use of nanoFez03in composite propellantThe synthesized a-Fe20 3 was characterized for bulk density, formulations resulted in � 50% improvement in burn rate. powder XRD, BET surface area and HRTEM. Two redox Keywordsnano iron oxide, large scale synthesis, titration methods, viz., permanganate and iodometric method permanganate, iodometric, titration, purity estimation,were studied for assay of nano a-Fe20 3 samples.

Crystallographic phase formation of iron oxide particles produced from iron nitrate by liquid flame spray with a dual oxygen flow

“…A heat treatment of iron citrate at 500°C also resulted in pure maghemite 29 . The two studies that reported synthesis of pure hematite from FeN‐CitA mixture, both had a calcination period of 4–6 h at 600°C in the end 30,31 . Since they performed no analyses before the calcination, we cannot be certain what kind of a phase composition was formed before it.…”
