Conclusions

  1. 1.

    Dissociation of the reaction product, silicon nitride, leads to an abrupt braking of heat liberation in the combustion zone. The nitride dissociation temperature controls the combustion temperature. The reaction depth in the reaction zone is less than unity. Wide burnout regions exist. The principles of combustion can be described qualitatively by the high-temperature dissociation model.

     
  2. 2.

    Silicon fusion in the heating zone leads to coagulation of the original reagent parcicles. Increase in the characteristic dimensions of the particles entering the reaction zone hinders the nitrogenization reaction. The effect of structural — “coagulation” — braking of combustion must be considered in explaining the principles of silicon combustion in nitrogen.

     
  3. 3.

    Filtration combustion occurs in the system with gas supply through the unburned portion of the specimen. In the pressure (p0=10–20 MPa) and relative density Θ0=0.4 range: considered, filtration does not limit the process.
