Detonation of mixtures of bistrinitroethylnitramine with carbon

The dependence of detonation rate on charge density is determined for bistrinitroethylnitramine and stoichiometric mixtures of it with carbon (soot, graphite with different particle sizes). A characteristic feature of dependences for mixtures of BTNENA with carbon is a discontinuity whose position corresponds to the following charge densities, g/cm$^3$ : 1.43 for a mixture with soot, 1.15 and $<$ 0.4 g/cm$^3$ for a mixture with graphite (particle size 10$^{-3}$cm and 5.6$\cdot$10$^{-3}$ cm respectively). The treatment of experimental results is provided.
