niobium processing
Four one-millimetre thick samples of niobium metal foil.
In the context of niobium processing, isostatic pressing is used to shape niobium powder into "green" (unfired) compacts. By applying pressure to the powder, the process creates these compacts to a density of approximately 60β65 percent of the theoretical maximum. Once shaped, these compacts undergo sintering in a vacuum at high temperatures to consolidate the metal and improve its mechanical properties.1
