High-purity beryllium powder possesses characteristics differing substantially from those of the normal powder that until recently has been the purest form available. These characteristics are compared and discussed, together with methods for consolidating the powder and treating the compacts. The techniques available for fabricating porous compacts and their applicability are also described.
