The synthesis method of aluminium oxynitride (AlON) powders by nitriding of Al/Al2O3 mixture under highpressure nitrogen is proposed. The novelty of this method consists in adding KClO4 or Mg(ClO4)2 and extra Al into the starting mixture (Al+Al2O3) to cause the exothermal aluminium oxidation reaction, which therefore initiates the aluminium nitriding reaction. The microstructure and phase composition of the AlON powders obtained by self-propagating high-temperature synthesis are demonstrated by means of SEM and XRD analysis. Diffuse reflection spectra of AlON powders have been measured and the values of band-gap energy have been calculated. Optical transmission and reflection characteristics of the AlON ceramic samples sintered from AlON powders at 1930°C have been studied. The influence of the technological parameters of ceramics production on their transparency is revealed – the most transparent sample is obtained from the powders synthesized with the Mg(ClO4)2 additive and sintered for 6 h.

“…There is a fertile field of opportunity here for the development of operando techniques, especially based on optical (e.g., infra-red) probes that may be profitably inserted into the SCS environment. In other variants of SCS, thermocouples have been used in the combustion tube to measure the combustion temperature and burning velocity [20]. Nonetheless, some degree of understanding of the mechanistic aspects of SCS may be gleaned by the use of thermal analysis (i.e., differential scanning calorimetry, DSC and thermogravimetric analysis, TGA) on the SCS precursors.…”

This is a perspective of the role that combustion synthesis, specifically solution combustion synthesis, has played in the development of ternary and quaternary metal oxide semiconductors, and materials derived from these compounds such as composites, solid solutions, and doped samples. The attributes of materials, collectively termed 'complex oxides' within the context of this discussion, are discussed in terms of their applicability in the generation of solar fuels from water splitting and CO 2 reduction, and environmental pollution remediation via heterogeneous photocatalysis.
