6-50mm yttria-stabilized zirconia Ball Grinding Bead
Its Zirconia content is close to 95% so it also called 95% Zirconia beads or high purity Zirconia beads. The Zirconia beads we sell is manufactured from Zirconia Oxide powder and Yttria Oxide powder with addtives under high pressure pressing. After pressing, the green beads are sintered at high temperature to form a tetragonal Zirconia Polycrystal (Y-TZP) microstructure.
The Zirconia beads are used for superfine grinding and dispersing of zero pollution, high viscosity, high hardness and so on. It is applied to the equipments like horizontal sand mills, vertical sand mills, basket mills, ball mills, attritors.
Applications
High quality microsphere grinding beads are produced from the consistent high quality yttria‐stabilized zirconia powder through the latest hydrolysis process. It have super grinding efficiency because of highest crushing strength, lowest wear loss. The qualities and properties reach the international advanced level. It is suitable for grinding material down to Nano size such as electronic ceramics; ceramic ink; MLCC; CMP and Photo Catalysts etc.

Advantages
1. High density ≥ 6.02g/cm3;
2. Very high wear and tear resistance;
3. Highest operating time is achievable;
4. Low contamination of the grinding product, therefore useable for high-grade grinding of pigments, dyes, pharmaceutical and cosmetic products;
5. Useable for all modern types of mills and high energy mills (vertical and horizontal);
6. Excellent crystal structure avoids bead breakage and reduces the abrasion of mill parts;
7. No radioactivity in comparison to ceramic beads made of zirconium silicate and therefore no contamication of the grinding product and no costly disposal of the beads.
