The media most used in all milling applications are made of zirconia. But if the purpose of ball-milling is to blend materials softer than zirconia, alumina media is recommended to avoid breaking the dispersed powder. Using grinding balls with different diameters, 3 or more, improves the particles dispersion in the ceramic slurries.

Ballmilling is a process of crushing and mixing materials together. In addition to producing nano ceramic powder, this method can also be used to mix powders. This method uses balls (alumina or zirconia balls) that circulate inside the vial. With each heat that the balls inflicts on the powder, the powder size decreases.
