Critical diameter of liquid explosives as a function of powder content

  • R. Kh. Kurbangalina


The dependence of the critical diameter (d*) of nitromethane (NM) on the content of aluminum, aluminum oxide, tungsten powders, carbon black, and talc and the dependence of the d* of tetranitromethane (TNM) on aluminum and aluminum oxide content have been experimentally investigated. The powder content was varied over'a wide range (0–75% by weight), as was the particle size. It was found that for NM mixtures the variation of d* is quite different from that for TNM. For powder particle sizes of 1–50μ the d* of the NM mixtures decreases with increase in powder concentration. The minimum value of d* is ten times less than the value for pure NM. In TNM mixtures d* increases monotonically with the amount of powder. It is assumed that this behavior of the NM mixtures is associated with the inhomogeneous structure of the detonation front in NM, a consequence of the particular reaction kinetics characteristic of nitromethane.
