“…A characteristic of these systems is that all reactants and products are in their condensed state (i.e., either solid or liquid melt), with negligible amount of vaporized components. When applied to the synthesis of refractory compounds and materials, the process is frequently called ''self-propagating high-temperature synthesis'' (SHS), also known as ''combustion synthesis'' or ''gasless combustion'' or ''solid flame'' (5)(6)(7)(8). Combustion synthesis has generated notable interest because of its potential for producing advanced materials, and many papers concerning this process have been published (9).…”

Self-propagating high temperature reaction waves, leading to the synthesis of advanced materials, are investigated in a variety of heterogeneous reaction systems by using a digital high-speed microscopic video recording technique. It is shown that, although on the macroscopic length and time scales, the reaction appears to move in a steady mode, on the microscopic level it has a complex character that is related to the reaction mechanism.

“…Here we present an example of a movie of a self-propagating high temperature reaction [38][39][40][41][42][43][44][45] in a stoichiometric mixture of titanium and silicon. In these reactions the material changes from a pressed powder to a ceramic pellet.…”

An application of nuclear physics, a facility for using protons for flash radiography, has been developed at the Los Alamos Neutron Science Center (LANSCE). Protons have proven far superior to high energy x-rays for flash radiography because of their long mean free path, good position resolution, and low scatter background. Although this facility is primarily used for studying very fast phenomena such as high explosive driven experiments, it is finding increasing application to other fields, such as tomography of static objects, phase changes in materials and the dynamics of chemical reactions. The advantages of protons are discussed, data from some recent experiments will be reviewed and concepts for new techniques are introduced.

“…After ignition, the combustion wave spreaded along a spiral trajectory from top to the bottom of the specimen. This spinning combustion wave is considered as an unstable combustion phenomenon and mainly caused by the lack of sufficient heat flux generated from the reaction to maintain the steady propagation of the planar front 28,29 . We refer it "normal combustion", compared to the explosion combustion; where the propagation velocity of the combustion wave can be up to 1000−4000 m/s 30 .…”

“…For the formation of compounds, it has been demonstrated empirically that the reaction will not be self−propagating unless the adiabatic temperature is beyond 1800K (T ad ≥1800K) [19][20][21] . The formula of theoretical adiabatic temperature is as follow 20,29 :…”

0.6 )Si 2 were prepared by combustion synthesis. The combustion mode, propagation velocity of combustion wave, combustion temperature and product structure were investigated. Specimens MoSi 2 , (Mo 0.9 Ti 0.1 )Si 2 , (Mo 0.8 Ti 0.2 )Si 2 , (Mo 0.7 Ti 0.3 )Si 2 , underwent spontaneously self−propagating combustion synthesis. However, the (Mo 0.6 Ti 0.4 )Si 2 and (Mo 0.5 Ti 0.5 )Si 2 specimens required a sustainable energy supply to complete the combustion synthesis reaction. There was no combustion synthesis reaction in specimen (Mo 0.4 Ti 0.6 )Si 2 . The combustion wave propagated along a spiral trajectory from top to the bottom of the specimen compacts in a layer by layer mode. The propagation velocity of the combustion wave reduced with the addition of titanium. The X-ray diffraction analysis showed that the Cll b -MoSi 2 and C40-(Mo,Ti)Si 2 type phases were formed during combustion synthesis. The intensity of diffraction peaks of C40-(Mo,Ti)Si 2 phase increased with Ti content.
