Solution combustion is an exciting phenomenon, which involves propagation of self-sustained exothermic reactions along an aqueous or sol-gel media. This process allows for the synthesis of a variety of nanoscale materials, including oxides, metals, alloys, and sulfides. This Review focuses on the analysis of new approaches and results in the field of solution combustion synthesis (SCS) obtained during recent years. Thermodynamics and kinetics of reactive solutions used in different chemical routes are considered, and the role of process parameters is discussed, emphasizing the chemical mechanisms that are responsible for rapid self-sustained combustion reactions. The basic principles for controlling the composition, structure, and nanostructure of SCS products, and routes to regulate the size and morphology of the nanoscale materials are also reviewed. Recently developed systems that lead to the formation of novel materials and unique structures (e.g., thin films and two-dimensional crystals) with unusual properties are outlined. To demonstrate the versatility of the approach, several application categories of SCS produced materials, such as for energy conversion and storage, optical devices, catalysts, and various important nanoceramics (e.g., bio-, electro-, magnetic), are discussed.

“…Hollow BaTiO 3 particles have been obtained by pyrolysis at temperatures between 600 and 1000 °C by using a confined reaction environment determined by droplets or aerosols, analogously to the use of templates 8. A chemically homogeneous BaTiO 3 powder composed of submicron‐sized hollow particles with extremely thin walls were also obtained at temperatures higher than 800 °C by the emulsion combustion method 9. At 700 °C, hollow barium titanate structures were prepared by chemical‐template solid‐state reaction starting from core–shell BaCO 3 @TiO 2 particles 4a.…”

This work aims to clarify the mechanism of formation of torus-like barium titanate (BaTiO 3 ) particles with a view to evaluating the properties of these hollow perovskite oxide crystals. Crystalline BaTiO 3 powders have been synthesized by hydrothermal treatment of titanium-based nanotubes and barium chloride in alkaline media at 90, 110 and 200°C for various reaction times. The possibility of obtaining hollow [a]

“…The small reaction field and short reaction period lead to the formation of nano-size ceramic particles [13]. This technology also known as calcination control of chemical additives (CCCA), has been used by researchers for the preparation of BaTiO 3 [14], Al 2 O 3 [15][16][17], ZrO 2 [18] , ␣-Al 2 O 3 -t-ZrO 2 [19], LiCoO 2 [20], Yttria stabilized zirconia [21], ZrO 2 -CeO 2 [22], ZnO [23], Fe 2 O 3 [23], CeO 2 [23], MgO [23] and ZnO-SiO 2 [24] fine powders. It is noteworthy that this procedure provides a unique and desirable situation for limiting the growth of the crystal sizes from unnecessary enlargement, seemingly caused by the incomplete combustion of the organics and the presence of char particles [17].…”
