Abstract
Beryllium powder-making has never presented major technical or economic problems, and several methods have been available for manufacturing the desired particle size ranges in the required degrees of purity. Several milling methods are capable of disintegrating or pulverizing brittle, friable metals. Beryllium cleaves readily along a single plane, and particles made by impacting are thin, jagged, and rather flat, much smaller in thickness than in any planar direction. Such milling of coarse chip or powder produces some powder of the desired fineness, and repeated passes are needed to attain practical production rates and yields.
