Yttria Stabilized Zirconia Beads

1. High crush strength, no breakage under high-speed impact.

2. Smooth surface, good sphericity.

3. High wear resistance, longer service life 30-50 times than glass beads, 5 times than zirconium silicate beads and 6-8 times than Al2O3 beads.

4. High density and excellent grinding efficiency


Yttria stabilized zirconia beads (Y-TZP), or YSZ beads for short, are a type of ceramic grinding media made primarily of zirconium oxide (ZrO2) with a small amount of yttrium oxide (Y2O3) added to stabilize the material. The incorporation of yttrium oxide enhances the strength and toughness of the beads, resulting in exceptional wear and fracture resistance. These properties make YSZ beads highly suitable for applications involving high-energy milling, particularly in the production of advanced ceramics that require significant impact forces.

The outstanding characteristics of YSZ beads are crucial in the manufacturing processes of electronic materials, pigments, and coatings, where the use of high-performance materials is essential. These beads are capable of withstanding intense grinding conditions and maintaining their structural integrity, ensuring consistent and efficient milling results.

In addition to their wear and fracture resistance, YSZ beads offer other advantages as well. They exhibit a high level of chemical inertness, making them compatible with various materials and reducing the risk of contamination during milling. YSZ beads are also known for their excellent thermal stability, allowing them to withstand high temperatures without significant degradation. This thermal resistance is particularly important in applications where elevated temperatures are involved, such as in the production of ceramic materials and coatings.

Overall, Yttria-stabilized zirconia beads (YSZ beads) are valuable grinding media  due to their remarkable properties, including strength, toughness, wear resistance, chemical inertness, and thermal stability. These attributes make them an ideal choice for demanding milling processes in various industries, contributing to the production of high-quality materials and products.
