Re-Establishing Filtering Capabilities of Machined Porous Beryllium Via Chemical Reduction and Cleaning.

摘要

Porous beryllium is furnished in sheets of varying sizes and thickness;it is therefore necessary that it be machined into specified sizes. A chemical reduction and cleaning procedure was devised to remove the disrupted surface,open the sealed pores of the material,and clean entrapped contaminates from the internal structure. Dimensional stability can be closely controlled and material size is of no consequence.
