Conclusion
In conclusion, it should be noted that the above-noted results of theoretical and experimental investigations of the combustion of carbon particles cover an intensity range leading to heating of the particles that does not exceed the boiling point Tb, (for carbon, Tb ∼ 4000°K). At such temperatures, the basic chemical reactions with carbon are heterogeneous in character, i.e., they occur at the surface of the solid phase. However, at high incident-radiation intensities, metastable heating of the particles to Ta ⩾ Tb is possible; chemical reactions will then occur in the gas phase. An analogous situation is possible in the action of radiation, for example, on drops of petroleum products or alkali-metal particles with a low boiling point.
