Title: HE formulation. Quarterly report, October--December, 1971

Abstract

A freeze drying process has been developed which alleviates the caking of high surface area HE powders upon drying and yields a light fluffy textured powder. Three batches of high surface area PETN treated with a surface active agent and two batches of high surface area (Micronizer) RDX have been freeze dried. The RDX powder had a low bulk density of about 0.25 g/cc. Batch sizes ranging from 2 to 10 pounds or more can be easily processed. Samples of the RDX, along with Micronized PETN (surface agent treated and heat stabilized, and untreated), Extex PETN made by a semi-continuous process, and appropriate control samples were each made into 80/20 Sylgard compositions and hand-loaded into ``Sunburst`` assemblies. Some of these assemblies were subjected to 100 C for 30 hours and 300 hours. All of the samples loaded with Micronized PETN and Extex PETN fired satisfactorily, burning to 6-mil thickness of the tapered rays. The RDX fired well also, burning to {approximately} 20-mil thickness of the rays. All the high surface area materials were, of course, very difficult to process at the 20% loading of Sylgard. Several of these samples were also subjected to a detonation velocity test in varying diametermore » channels. The Micronized PETN behavior was similar to Extex-type PETN.« less
