Solution combustion synthesis (SCS) of zinc oxide was performed using a binary fuel, glycine and citric acid. It was established that combustion occurs due
The possibility of synthesizing different crystalline modifications of alumina Al2O3 by combustion reactions of a mixture of aluminum nitrate with glycine has been analyzed. Aggregated powders of γ-Al2O3 that do not transform into the corundum structure after annealing at a temperature of 1000°C have been prepared. The influence of the synthesis conditions on the specific surface area, bulk density, porosity, and morphology of alumina particles has been investigated.
A multicomponent solid electrolyte of composition Ce0.8(Sm0.75Sr0.2Ba0.05)0.2O2 − δ has been synthesized by three different techniques: solid-state reaction, laser evaporation, and the glycine nitrate process. Its microstructure, sintering kinetics, and electrical properties have been studied in relation to the synthesis technique. Ceramics produced using laser evaporation consisted of submicron (0.2 μm) grains and offered the highest electrical conductivity: 27 × 10−3 S/cm at 873 K.

Solution-combustion synthesis (SCS) of MZrO3 zirconates (M = Ca, Sr, Ba) in an open reactor with glycine as a fuel was studied both experimentally and theoretically. Calculated thermal effects of the above SCS reactions were found to reasonably agree with experiment. The measured thermal effects of SCS reactions (ΔTmax) as a function of fuel/oxidant ratio (φ) exhibited a maximum within the range φ = 0.9–1.3 arising due to increasingly growing radiative heat loss from the open surface of burning reactive mixture. The occurrence of self-sustained SCS reactions yielding CaZrO3, SrZrO3, and BaZrO3 was found possible for φ ≥ 0.4, 0.3, and 0.4, respectively.

A cathode material for lithium-ion batteries–LiNi1/3Co1/3Mn1/3O2–was prepared by solution combustion synthesis and characterized by XRD, SEM, and galvanostatic charge/discharge cycling. The sample...
