Sputter deposition of porous thin films from metal/NaCl powder targets [PDF]
, 2019 A method to deposit porous thin films is elucidated. For this purpose, NaCl powder was mixed with a metal powder, cold pressed, and used as a target material in order to deposit a metal/NaCl thin film by DC magnetron sputtering.

Melt Damage and Prevention of Gas Nozzle Tip in Close-Coupled Gas Atomization
JGas atomization is one method for producing fine metal powder. In close-coupled gas atomization, a high-speed gas jet is ejected near the molten metal, and the molten metal is further broken down in the shear layer at the outer edge of the jet, producing
