Zirconium metal powder is vastly used in aerospace and military as a metal fuel because of its high combustion rate and heat. To comply with the special requirements for aerospace and military applications, zirconium particles are coated respectively with ferrite nanoparticles–FeOOH, Fe2O3, Fe3O4 nanoparticles to form a core-shell structure [1]. This process alters the combustion performance of the coated zirconium dust. In this study, scanning electron microscopy, X–ray diffraction, thermogravimetry and differential scanning calorimetry are used to examine the micromorphology, phase composition, crystal structure, thermal stability and reactivity of the three kinds of coated zirconium particles [2,3]. The combustion behaviour of FeOOH–coated zirconium particles, Fe2O3–coated zirconium particles, Fe3O4–coated zirconium particles in the air is explored and presented comparatively. It was concluded that with the coating layer of coated zirconium particles generating a replacement reaction with the inner core zirconium [4,5]. The inner zirconium induced an oxidation-reduction reaction with oxygen and Fe2+ was oxidised at high temperatures.
