Data from sieve analyses of HMX and HMX recovered from LX-04-1 has been compiled for correlation to quality parameters. Particle size distributions on HMX received from LRL have been completed along with other HMX lots specified by them. Sieve analysis of recrystallized PETN was obtained using the now normal procedure for HMX. A statistical investigation of production LX-04-1 examined the dependence of density, elongation, and ultimate tensile strength on particle size distributions ({Pi}) and Viton content. The {Pi} was found to correlate well with density, increases in fines decreasing density. An experimental to determine the effect of binder solvent on HMX {Pi} during removal of Viton from pressed LX-04-1 was performed. This study has indicated no drastic effect on the distribution by the length of time the binder solvent is on the material. HMX and recrystallized PETN surface area measurements obtained form the Perkin-Elmer sorptometer are tabulated in this report. Recrystallized PETN has been examined under the microscope and counts made on the number of crystals with given shape. A frequency distribution was calculated for each group present in a 1 mm{sup 2} area. Experiments to determine the extent of grinding or reduction of particle size of HMX agitated in an ultrasonic vibrator for increasing times have been done. The data have indicated a time of three--five minutes is adequate to disperse agglomerates without undue breaking or grinding of solid crystals. It is possible to do some grinding under severe conditions in the ultrasonic bath.
