Ceria Stabilized Zirconia Bead is also one of typical ceramic grinding media. As the material contains “Cerium”, the density of ceria stabilized zirconium oxide is about 6.2 g/cm3, which is the highest among the different types of ceramic grinding materials. Because of this feature, Ceria-Zirconia beads can be used to mill even high viscosity materials, in which other media may float.
