Dissemination of Solid and Liquid BW Agents
Abstract
Current theoretical investigations relating the interparticle contact energies to mechanical properties of compacted powders are described. Bg (lot SCH-63-109) used in flight tests was found to be more difficult to compact than Bg (lot 17). A new approach to obtain the energy of compaction from Instron data is presented. Agent LX, like other highly elastic materials, was found to be difficult to compact, has a comparatively high compaction shear strength, and a tensile strength too low to measure. An evaluation was made of the buoyant force corrections for the BET adsorption method to measure total surface area. Total surface area and rugosity measurements were made for spray-dried saccharin, agent LX, and egg embryo. A study of the effects of humidity (from 0 to 100 percent R.H.) upon the formation and decay of a ground powdered sugar aerosol is reported.
