A Melt-Cast Composition Based on NTO and FOX-7

A melt-cast composition containing NTO, FOX-7, TNT, Al and wax was prepared and tested. The viscosity of the melted composition was measured. Its sensitivity to impact, friction, shock wave and jet impact were determined, and its thermal stability and ignition temperature were established. Some detonation properties of the composition were investigated. The heat of detonation was measured using a calorimetric bomb. The detonation pressure and velocity were determined in a plate-dent test. The results of a cylinder test were used for the determination of the Gurney energy, the detonation pressure and energy, and the so-called effective exponent of the expansion isentrope and the JWL equation of state of the detonation products.
