    Abstract

    Mixtures of liquid oxygen (LOX) and liquid natural gas (LNG) are very attractive as commercial explosives because they exhibit very high brisance, or shattering power, and because the basic materials are readily available and inexpensive. However, the mixtures can be quite dangerous if mishandled, and there is little or no information available concerning the handling hazards. The objective of this program was to obtain such information by conducting a series of drop tests to characterize the impact ignition and reaction intensity behavior of various LOX-LNG mixtures and to determine whether the addition of an inert inhibitor would change the reaction intensity or the impact sensitivity. Impact tests were conducted using pentaerythritol tetranitrate (PETN), and the results were compared with those for the various LOX-LNG mixtures.
