A new arrangement of matter is developed which can be formulated to be a high explosive, a propellant or a gas generator. The new arrangement of matter in its explosive embodiment is known as a eutectic microknit explosive (EMCX) in which an essentially anhydrous eutectic mixture of ammonium nitrate, soluble explosive, and other oxidizing salts is mixed with surfactants and organic fuels while the eutectic mixture is molten, and a microcrystalline property is created which imparts a hard, machinable characteristic to the arrangement of matter. The invention includes three processes for making MCX compositions; (1) dissolving surfactants, crystal-habit modifiers, thickeners or combinations into the molten eutectic mixture in a manner which permits supercooling with subsequent solidification; (2) forming an unstable oil-continuous emulsion as a preliminary step, followed by a controlled disruption of the oil-phase continuum which causes the composition to solidify after supercooling, and (3) retarding crystal nucleation in salt-continuous emulsions by introducing surfactants, thickeners, crystal-habit modifiers or combinations, along with immiscible fuels, resulting in supercooling and subsequent solidification to a hard composition.

An arrangement of matter which is a solid, microcrystalline explosive, propellant or gas generator, comprising in combination: an essentially anhydrous mixture of ammonium nitrate and soluble explosives(s), surfactant(s), hydrocarbon fuel(s) and other inorganic oxidizer salt(s), including at least one such salt which is not a nitrate salt, involving the intimate mixing or dissolving of ingredients while they are in the molten state, the intimately mixed fluid having the property of permitting the molten salt(s) to be supercooled before the occurrence of crystal nucleation and reversion from the fluid state and wherein moisture which may be present is water of hydration or because of the hygroscopic nature of said oxidizer salts or explosive and is limited to 3% maximum by weight of the composiition.
