Impact Sensitivity of Wetted Primary Explosives as Determined by the Ball Drop Test

The effects of a number of liquids and liquid mixtures in sensitizing primary explosives were investigated by the ball drop method. Partly wetted lead azides were found to exhibit enhanced sensitivity to impact as compared to like compounds in the dry state. Lead styphnate and tetracene were desensitized by all experimental liquids. A tentative explanation of this effect is advanced in terms of the role played by liquids in causing desensitization or sensitization, according to the degree of wetting and the existence of confinement which would prevent dissipation of impact energy.
