Solid combustion synthesis of β SiC powders

Development of novel ceramic processing

“…A self propagating reaction front rapidly moves through the reactants completely converting them into nitrides. A solid combustion synthesis of SiC powder is produced by an exothermic reaction of silicon powders with carbon black and charcoal powders at an ignition temperature of 1250 to 1300 ° C [71]. High temperature reactions in solar furnaces and hydrothermal processing are also used to produce fine powders.…”

Finite-difference modelling of self-propagating high-temperature synthesis of materials

“…The weak exothermic reactions, such as Si + C ---* SiC and Ti + Ni -+ TiNi lie well within the "No SHS" zone and the "thermal explosion" method must be used to produce a reaction. reactions, Tstar t = 298 K unless indicated Si + C ~ SiC [28] Ti + Ni ~ TiNi [29] 9Cu + 4A1 ~ Cu9A14 [30] 3ZrO2 + 4AI + 3C----~ 3ZrC + 2A1203 [15] Ti + AI---~ TiAI [31] Mo + 2Si ---* MoSi 2 [32] 2Ni + Si --4 Ni2Si [33] Ni + AI ---* NiA1 [34] Ti + C--~ TiC [35] Ti + 2B ~ TiB 2 [36] 3TiO 2 + 4A1 + 3C ---* TiC + 2A1203 [15] ( The effect of preheating on the SHS reaction Ti + AI ~ TiAI can also be seen in Table 3. It has been reported by Yi et al [31] that preheating above 373 K is required to produce a steady SHS reaction.…”

Mn+1AXn Phonon Density of States: Ti3AlC2 and Ti3SiC2 Simulation and Experimentation Results

“…As pure polycrystalline compounds synthesis via solid state means is difficult due to the retention of intermediate phases, whilst synthesis remains difficult via melting and solidification due to decomposition above a critical temperature [3]. Although difficult to synthesise, some members of the MAX phase family such as Ti 3 SiC 2 have been well characterised in their polycrystalline form with their structure [4,5], properties [6,7], potential applications [7], and synthesis [4,[8][9][10][11][12][13][14][15][16] familiar to many materials scientists. Producing sizeable single crystals is difficult, and obtaining information e.g.…”
