Yttria Stabilized Zirconia Beads are manufactured from dry Yttria Stabilized Zirconia powder by high compaction press. They was sintered at a high temperature to form a Tetragonal Zirconia Polycrystal(Y-TZP) microstructure. The highest bending strenghth and fracture toughness was considered the first choice of grinding media to mill the most sensitive powder or slurry.
