The media media most used in all milling applications are made of zirconia. But if the purpose of ballmilling 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.
