Ap. Ershov et al., A study of the interaction between the components of heterogeneous explosives by the electrical-conductivity method, COMB EXPL R, 36(5), 2000, pp. 639-649
The detonation of TNT/RDX alloys is studied by the electrical-conductivity
method. The measurement technique is developed with correction for the defo
rmation of electrodes in the explosion. The maximum electrical conductivity
of pure TNT was approximate to 25 Ohm (-1).cm(-1). The addition of RDX\ de
creases the electrical conductivity and width of the conducting zone, which
, is, apparently, connected with the formation of diamond. It is shown that
the RDX particle size plays an important role. With equal mass fraction, t
he conductivity of the sample is several times smaller for micron particles
than for millimeter particles. This fact is explained by the different deg
ree of mixing of the detonation products of the heterogeneous-explosive com
ponents.
