ABSTRACT
The possibility of self-sustained solid-solid detonations (SSD) in Mn+S mixtures has been investigated. Charges 50 mm in diameter under different degrees of confinement were used. The initiation charges used include nitromethane, tetryl, and C-4. No self-sustained SSD were observed in the present study. Neither did the degree of confinement nor the type or weight of the initiation charge appear to make a significant difference in the results obtained. The shock and reaction front are initially coupled but decay rapidly. Decoupling occurs after about 25 mm of propagation when the shock has decayed to about 2.5 km/sec which corresponds to the estimated sound speed of the reactant. The lack of significant feedback of the chemical energy released to the shock via work done by the expansion of the solid products is probably the cause for failure to obtain SSD in Mn+S.

    We measured the velocity of shock waves generated by the detonation of a high explosive in a stoichiometric (equimolar) mixture of Zn and S powders. The initial decrease in the velocity of the shock wave in a sample was then found to be followed by a remarkable increase in the velocity of shock...
