Dry grinding is relatively efficient for most brittle materials, but at small particle sizes (below 50 microns) there is
a tendency for particles to agglomerate or cake. There are many grinding aids to prevent caking. Water, alcohol,
solvents, and other liquids can be added to create slurries whose medial particle size after grinding can be well
below 10 microns, but for most analytical techniques the liquid must be removed before analysis.
