Agglomeration of Powder
Amongst the several PCAs used, stearic acid is the most common. The PCA adsorbs on the surfaces of the powder particles and minimizes excessive cold welding of powder particles amongst themselves and/or to the milling container and the grinding medium; this inhibits agglomeration of powder particles. The PCA is most commonly added whenever ...
