AbstractFor combustion of powdered and granulated 5Ti + 3Si mixtures in a cylindrical channel, we explored the retarding action of impurity gases released from Ti particles of varied particle size. Green mixtures for combustion experiments were prepared from: (a) coarse and fine Si powders and (b) Ti powders of the following fractions:

AbstractSynthesis, characterization, and applications of the CoFe2O4 and M-CoFe2O4 (M = Ni, Zn, Mg, Cd, Cu, RE) ferrites produced in several routes, including combustion synthesis, were overviewed and systemized. Our collection may turn interesting to those engaged in research and development of magnetic materials.

AbstractCombustion of Me + 2B, (Me1 + Me2 + Me3 + Me4) + 8B, and (Me1 + Me2 + Me3 + Me4 + Me5) + 10B mixtures (Me = Ti, Hf, Nb, Zr, Ta) aiming at the preparation of a high-entropy metal diboride by SHS method was studied by using XRD and SEM analyses. We succeeded to prepare high-entropy diboride [TiHfZrNbTa]B2 by SHS method from the above mixtures...

AbstractNanoscale NiCr2O4 spinel powders were prepared by solution combustion synthesis (SCS) from aqueous solutions of chromium/nickel nitrates as oxidants, urea as a fuel, and nitric acid and characterized by SEM/EDS, XRD, and porosity measurements. The catalytic activity of synthesized powders in conversion of CO to CO2 was determined and compar...

AbstractAmorphous nanoscale zero-valent iron (nZVI) was synthesized via facile auto-combustion reaction of sodium borohydride (NaBH4) with α-Fe2O3 in aqueous solution. The amount of NaBH4 for the combustion reaction was evaluated and optimized. The prepared nZVI were characterized by XRD, HRTEM, and EDS. Protective 2–3-nm oxide layer formed on the ...

AbstractZn-substituted copper nanoferrites Cu1 – xZnxFe2O4 (x = 0.0, 0.25, 0.50, 0.75, 1.0) were prepared by solution-combustion synthesis (SCS) and their structural, dielectric, and magnetic properties were characterized by XRD, magnetic, and impedance measurements. Based on X-ray diffraction patterns, various structural parameters such as lattice...

AbstractProducts formed upon combustion of [40 FeSi + 30 FeSiN + 30 ZrSiO4 (zircon)] + xAl (x = 1.0–10, all figures in wt %) mixtures in nitrogen gas under pressure were characterized by XRD and SEM, with special emphasis on the impact of aluminum additives. Nitrogen content of combustion products and burning velocity were measured as a function of...

AbstractThermochemical interactions of Fe, Co and Ni precursors with thiourea, ammonium thiocyanate, and sulfur in the wave of flameless combustion of RDX in ballasted systems were explored. In case of thiourea or ammonium thiocyanate as a source of sulfur, combustion-synthesized sulfides CoS, NiS and oxides Fe2O3, Fe3O4 turn encapsulated in a visc...
