Microstructure of heterogeneous mixtures for gasless combustion

The microstructure of a mixture for gasless combustion and its compactability were studied. The electrical conductivity, thermal conductivity, and burning rate of the mixture were measured, and metallographical studies were performed. It was found that particle shape and the ability of the particles to form a continuous skeleton play a determining role in the gasless combustion of the mixture. Accounting for this fact allows one to explain some experimental results that are inconsistent with the conventional theory of gasless combustion.
