Interaction of carbonaceous materials with gunpowder gases

Combustion, Explosion and Shock Waves Aims and scope

Conclusions

We have investigated the completeness of the interaction of various carbonaceous materials with gunpowder gases in the ballistite gunpowder combustion wave. We have shown that the limit in the carbonaceous material content, above which a change occurs in the interaction of the CM with the gunpowder combustion products, depends on the material's specific surface and is independent of the oxidizer-excess coefficient of the gunpowder.

For the highly dispersed (200–250 m2/g) materials (carbon fiber and KGO-250 carbon black) this limit is about 50% of the thermodynamic value, which equals 10% for the gunpowder N (α=0.55) and 17% for gunpowder A (α=0.72), while for the carbon black PM-15, which has a lower specific surface (15 m2/g) it is about 30%.

The incomplete combustion is explained by the presence of kinetic impediments in the interaction of the carbon with carbon dioxide and water.
