“…Thorough studies were conducted regarding the SHS in the binary systems Mo–Si and Mo–B, including the mathematical modelling of the combustion mechanisms, investigations of the impact of the mechanical activation (MA) on the reactivity of the mixtures, as well as studies of the influence of the different raw materials, samples size, and stoichiometry of the reaction mixture on the combustion kinetics (combustion regime, combustion temperature and velocity) and phase composition of combustion products. However, only a limited amount of data concerning the SHS of ceramics in the ternary Mo–Si–B system was published.…”

High-temperature materials attract a growing interest from both the scientists and engineers, since the increase of the operating temperatures is crucial for the enhancement of many energy conversion processes. Another area of application of high-temperature materials is high-velocity air flight, where the ultra-high temperature ceramics (UHTCs) are pivotal for the creation of robust nose tips and leading edges of the skins of high-velocity jets. Compounds of refractory metals with silicon, such as TaSi 2 , MoSi 2 , ZrSi 2 , are characterized by unrivaled resistance in aggressive environments. However, most of them are not suitable for application as high-temperature structural materials due to the low mechanical properties. Therefore, they are frequently used as a constituent for the high-temperature composite materials such as TaSi 2 -SiC, ZrC-MoSi 2 , ZrB 2 -MoSi 2 , ZrB 2 -ZrSi 2 . One of the most convenient ways of producing these composite materials is self-propagating hightemperature synthesis (SHS), known for its high productivity, energyefficiency, and ecological safety. This review summarizes the latest developments of the SHS of the silicon-based high-temperature ceramics.
