“…As one of the most important propellants, the high burning rate solid rocket propellant has been extensively used in terms of operational rockets, missiles, satellites, and space shuttle launch vehicles. Many efforts have been devoted for developing novel propellants with high burning rate to fulfill the ever-growing and challenging requirements. − The burning rate can be tuned by the addition of high energetic materials, combustion catalysts, and even by adjusting the particle size of oxidizers in the solid rocket propellants. − In particular, chromate as a transition metal combustion catalyst is capable of increasing the burning rate of solid propellants. − Ammonium perchlorate (AP) with the particle size of about 1 μm, namely, fine AP (FAP), has been widely used as an oxidizer to promote the burning rate of composite propellants. , On the other hand, hexanitrohexaazaisowurtzitane (CL-20), a novel high explosive, has aroused great concerns to be used as a high energetic additive to improve the energy of composite propellants. , …”

The chromate nanoparticles such as CoCr2O4, NiCr2O4, CuCr2O4, and ZnCr2O4 were prepared by a modified sol–gel method. The structural and morphological properties of the chromate nanoparticles were characterized by X-ray diffraction (XRD) and a scanning electron microscope (SEM). The catalytic effects of chromates on the thermal decomposition of fine ammonium perchlorate (FAP) and hexanitrohexaazaisowurtzitane (CL-20) were studied by the TG-DTG measurements. Results show that the addition of CoCr2O4, NiCr2O4, CuCr2O4, and ZnCr2O4 nanoparticles makes the activation energies for the thermal decomposition of FAP decrease by 93.9, 94.0, 83.1, and 67.0 kJ·mol–1, and the thermal decomposition temperatures decrease by 45.0, 24.9, 57.7, and 38.8 K respectively. On the other hand, a similar trend exists in the case of the thermal decomposition of CL-20. Therefore, the addition of nanochromates shows high catalytic efficiency on the thermal decomposition of both FAP and CL-20 components, which would be beneficial to promote the burning rate of propellants containing FAP and CL-20 components.

“…Singh et al [14] also explored the catalytic behaviour of Cd nanocrystals and CdFe 2 O 4 on composite solid propellants and found CdFe 2 O 4 to be better than Cd nanocrystals in increasing the composite propellant's burning rate. Singh et al [15] synthesised and characterized nanoferrites of Mn, Co, Ni in the form of nanorod, nanosphere, and nanocube morphologies. They studied the catalytic effect of these nanoferrites on AP and found the order of effectiveness to be:…”

In the present work, various propellant compositions were prepared by incorporating strontium ferrite (SrFe12O19) in an ammonium perchlorate (AP), aluminium powder and hydroxyl-terminated polybutadiene (HTPB) based standard composite propellant. The compositions were then studied by assessing the effect of the SrFe12O19 content on the propellant slurry viscosity, and the mechanical and ballistic properties. The results showed that as the percentage of SrFe12O19 in the propellant was increased, the end of mix (EOM) slurry viscosity, tensile strength and E-modulus increased, while the elongation decreased. The ballistic properties data revealed that the burning rate of the propellant composition containing 1.0% SrFe12O19 was enhanced by around 15% (at 6.86 MPa) compared to the standard composition burning rate.

“…Spinel ferrites play an important role in technological applications. Their interesting electrical, magnetic, and dielectric properties make them useful in many applications, such as electronic devices, sensors, memory devices, data storage, and telecommunications [1][2][3][4][5][6][7][8][9]. Recently, the possibility of preparing ferrites in the form of nanoparticles (NPs) has opened a new and exciting research field with revolutionary applications, not only in electronic technology but also in the fields of biotechnology [10] and water treatment [11], due to their nanometer size, superparamagnetic properties, and a high surface-to-volume ratio [12,13].…”

Adsorption of Pb(II) from aqueous solution using MFe2O4 nanoferrites (M = Co, Ni, and Zn) was studied. Nanoferrite samples were prepared via the mechanochemical method and were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), micro-Raman, and vibrating sample magnetometry (VSM). XRD analysis confirms the formation of pure single phases of cubic ferrites with average crystallite sizes of 23.8, 19.4, and 19.2 nm for CoFe2O4, NiFe2O4, and ZnFe2O4, respectively. Only NiFe2O4 and ZnFe2O4 samples show superparamagnetic behavior at room temperature, whereas CoFe2O4 is ferromagnetic. Kinetics and isotherm adsorption studies for adsorption of Pb(II) were carried out. A pseudo-second-order kinetic describes the sorption behavior. The experimental data of the isotherms were well fitted to the Langmuir isotherm model. The maximum adsorption capacity of Pb(II) on the nanoferrites was found to be 20.58, 17.76, and 9.34 mg·g−1 for M = Co, Ni, and Zn, respectively.
