High performance and reactivity of ultra-ﬁne aluminium is the present new area of interest in aerospace and defence applications. Ultra-ﬁne aluminium is an important ingredient in propellant compositions and formulations, which signiﬁcantly improves the performance parameters of rockets. This paper discusses the characterization of synthesized ultra-ﬁne aluminium, such as active (metallic) aluminium content, bulk density, X-ray diffraction, surface area (Brunauer–Emmett–Teller), scanning electron microscopy, transmission electron microscopy, thermal analysis and X-ray photo-electron spectroscopy. It is observed that the maximum metallic aluminium content of 85.93% was obtained by a gas volumetric method. The synthesized ultra-ﬁne aluminium particles will greatly promote the application of these particles in composite propellants.
