Favorable Conditions

It is shown that the organization of co-current flow of the reacting gas during combustion synthesis of porous oxynitride materials leads to intensification of the process. The flow creates favorable conditions for directed heat and mass transfer in reacting media. It results in super-adiabatic heating of the products in the area of the combustion wave. Thus, macrokinetic parameters of the combustion synthesis exceed 10 % than the ones that had been obtained without forced filtering of gaseous reactant. Organization of the process in flowing of the reacting gas allows us to obtain materials with conversion ratio up to 0.95 under the combustion rates up to 0.8 mm/s and maximum temperature in the combustion wave up to 1900 °C.
