“…Combustion is a series of complex chemical reactions between an oxidant and a fuel together with the heat production and/or light in the form of either glow or flames. The combustion concept uses the art of fast thermal degradation of starting material chemicals by reacting with O 2 ; it has been effectively applied for the preparation of various nanoscale metal oxides . This method contains some disadvantages such as contamination because of the carbonaceous residue, nanoparticles agglomeration, and no control on nanoparticles morphology.…”

Summary With the increasing demand and depleting trend of commercial energies, it has forced the researchers all over the world to accelerate research and development in the area of renewable energy. Currently, unique and interesting features of binary compounds have gained more attention by researchers, and it became a favourite research topic among various groups of researchers around this world. It was noticed that strontium titanate (SrTiO3) consists of several extraordinary properties that can apply for miscellaneous applications especially for energy storage, fuel cells, as well as to generate hydrogen fuel via photocatalysis process. Besides that, it was noticed that SrTiO3 can be synthesised in different pathways. The method of preparation and amount of precursors can affect the surface properties of SrTiO3. Thus, this article presents a critical review on how SrTiO3 synthesis methods affect its surface morphology and the applications of SrTiO3 in various fields.

“…This process starts at low temperature, with the help of an external heating source, followed by subsequent exothermic reaction between the oxidiser and fuel; this exothermic the reaction provides necessary heat to further carry out the reaction in the forward direction to produce nanocrystalline powders as the final product. Several organic fuels such as urea, glycine, oxalyl dihydrazide, sucrose, glycine-nitrate, urea-formaldehyde have been tried to synthesize nano-ceramic powders [4][5][6][7][8].…”

Nanocrystalline zirconia powders stabilized with varying concentration of yttria (YSZ) were synthesized following urea solution combustion route. Thermogravimetric analysis combined with differential scanning calorimetry was carried out for the intermediate gel for analyzing reaction kinetics. The final products were characterized by X-ray diffractometry, transmission electron microscopy and specific surface area measurements. Sintering behavior of theses powders were studied. The powder quality is poor in respect of surface area and sintered density.

Synthesis of magnesium aluminate spinel (MgAl2O4) was investigated by employing ball milling and co-precipitation methods. The starting materials (aluminum hydroxides) were obtained from the purified sodium hydroxide leaching solution of black dross. The characteristics of the synthesized spinel was analyzed through X-ray diffraction (XRD), scanning electron microscopy (SEM) images. In this work, the effect of calcination temperature and time on the formation of spinel by the two methods was compared. Calcination temperature showed a great effect on the formation of spinel in both methods. The results showed that the co-precipitation method has many advantages over the ball milling method. In ball milling method, complete conversion of the starting materials to spinel was impossible even at 1500 °C, while complete conversion to spinel was accomplished at 1000 °C for 5 h by the co-precipitation method. The average size of the spinel synthesized at these optimum conditions of the co-precipitation method was about 17 nm. A process can be developed to synthesize spinel from the black dross which is regarded as hazardous materials.
