This invention involves a process for improving the energy and ignitability of a metal slurry gel rocket fuel by the use of an energetic metal compound of higher energy than the parent metal. An energetic metal compound is added slowly to a liquid rocket fuel with appropriate stirring to form a suspension of the metallic compound in the liquid fuel. To this is added a small quantity of a gelling agent, such as silicon dioxide, with stirring, to form an energetic metal fuel gel. The energetic metal compound is prepared by using a high purity metal in the form of a wire. As an example, a sample of aluminum wire weighing 2.26 grams is supplied with an external source of high voltage and amperes, while the wire is in an environment of an inert gas (e.g., argon) under about 40 atmospheres pressure, to achieve electrical explosion of the wire. The product produced is a fine, gray, non-conductive powder in high yield. This powder contains aluminum and argon. This powder can be used to replace the aluminum of a prior art thixotropic fuel gel to obtain a thixotropic fuel gel with an improved performance with higher energy.
