A comparative study on combustion synthesis of Ti–Si compounds

Formation of Mo−Si−Ti Alloys by Self−propagating Combustion Synthesis

“…The difference in recorded and theoretical adiabatic temperature appears to be dependent on the composition of the raw material, reaction environment and heat exchange with the surrounding. Similar experimental evidences are reported earlier in the combustion synthesis of silicide, boride and carbide 25,26,33 . The theoretical adiabatic temperature of Ta 2 C, TiSi and NbB 2 are 2600K, 2000K and 2400K, respectively.…”

“…The theoretical adiabatic temperature of Ta 2 C, TiSi and NbB 2 are 2600K, 2000K and 2400K, respectively. The measured combustion temperatures reported were 1963K 33 , 1603K 25 and 1873K 26 , respectively, which are much lower than their theoretical adiabatic temperature.…”

“…The underlying basis of SHS relies on the ability of highly exothermic reactions to be self−sustaining and, therefore, energetically efficient [20][21][22] . Combustion synthesis is an important method to prepare intermetallics compounds like MoSi 2 , Ti−Si and Nb−B [23][24][25][26][27] . However, there is no report in the literature on the combustion synthesis of Mo−Si−Ti alloys.…”

Influence of reactant particle size on products of self-propagating high-temperature synthesis in 30wt.% Cr–Ti–B4C system

“…Self-propagating high-temperature synthesis (SHS), also termed combustion synthesis, has been widely utilized to produce a variety of materials including ceramics, ceramics-metal composites and intermetallics [1][2][3]. This method offers several benefits with respect to obtaining lower energy consumption, higher time efficiency and higher product purity [4].…”

Combustion synthesis of TiN–Ti silicide and TiN–Si3N4 composites from Ti–Si3N4 powder compacts in Ar and N2

“…Combustion synthesis, particularly in the mode of self-propagating high-temperature synthesis (SHS), takes advantage of the self-sustaining merit from highly exothermic reactions and hence has the potential of low-energy requirement, short processing time, simplicity of facilities, and high-purity products [21][22][23]. Although formation of monolithic TiN [24,25] and various titanium silicides [26,27] has been studied by means of SHS, the preparation of the TiN-TiSi 2 and/or Ti 5 Si 3 composites has not been well characterized. Similarly, limited studies have been reported on synthesis of the TiN-Si 3 N 4 composite by SHS.…”
