This article compares different media materials in terms of their wear resistance and impact on mill wear. Also discussed is the effect of individual media shape and media size distribution on the dispersion efficiency. A recently developed modification of wear resistant media material (Ce-TZP) (Mill Mates®/ Mill Mates Plus®) will be introduced and its properties compared with the other types of zirconia ceramics currently used as media material (Y-TZP and Mg-PSZ).
