COMPARISON OF MECHANICALLY BALLED MAGNESIUM WITH ATOMIZED MAGNESIUM FOR USE IN PYROTECHNIC COMPOSITIONS
Abstract
Results of a variety of physical and chemical tests indicate that, with a few minor exceptions, balled magnesium meets the requirements of Military Specification 14067-A for 30/50 mesh magnesium powder. The balled magnesium was found to be less reactive than the currently prescribed atomized magnesium, both with water and as a result of exposure to high relative humidities, as determined by gas evolution, weight gain, and surface area measurements. Results of vacuum stability tests at 167F and 230F for thirty days indicate that the balled magnesium has greater stability than atomized magnesium; the thermochemical and sensitivity data for balled magnesium and atomized magnesium are comparable. In performance characteristics such as candlepower, burning rate, and luminous efficiency, similar results were obtained with the two materials. These results indicate that the Reade balled magnesium can be used as an alternate for atomized 30/50 mesh magnesium in consolidated pyrotechnic compositions.
