Process Control Agent - an overview ScienceDirect Topics

A process control agent (PCA) is usually used in the process of mechanical alloying to avoid cold welding and bonding between the powder particles and the balls and the agglomeration of powder during milling, which is also noticeable for some alloy systems in the solid–liquid reaction ball milling process (Chen and Chen, 2006 ).
