Ultrasonic cleaning baths, common in many chemical laboratories, have been used to disperse particle agglomerates prior to automated particle size analysis and have been proposed for disassembly of consolidated powders of crystalline HMX (cyclotetramethylene-tetranitramine). This paper reports the effects of a Branson ultrasonic bath on coarse HMX crystals. Three experimental approaches are presented. The following observed effects are discussed: reduction of particle size, alteration of particle morphology, and fracture of individual crystals.
