Zirconia Microsphere

1. High crushing strength, fracture durability, and superior wear resistance even under high speed impact.

2. Smooth surface, good sphericity.

3. High density and excellent grinding efficiency for grinding materials down to nano size.

4. Significant cost and waste reduction


Zirconium beads go by many names around the world: Mahlperlen in Germany. Bolas de Moliendas in South America. Pearls in Europe. Zirconia beads in Asia. But whichever corner of the globe you call home, whatever you call the beads, one thing is clear— Sanxin Zirconia beads Grinding Media is the right ceramic grinding media for you.

Zirconia microsphere (SXYZV Series) are produced using high-quality yttria-stabilized zirconia powder through the latest hydrolysis process. These beads exhibit outstanding grinding efficiency, thanks to their high crushing strength and minimal wear loss. They adhere to international standards in terms of quality and properties, making them reliable and effective grinding media. Zirconia microsphere beads are well-suited for grinding materials to the nano size range, including electronic ceramics, ceramic ink, MLCC (multi-layer ceramic capacitors), CMP (chemical mechanical planarization), and photo catalysts.

Ceramic Zirconia Mircrophere Beads

The utilization of high-quality yttria-stabilized zirconia powder in the manufacturing process ensures the beads' excellent properties. The hydrolysis process enables the production of uniform and finely controlled microspheres, which contribute to their enhanced grinding performance. These beads possess a high crushing strength, enabling them to withstand significant forces during grinding without breaking or deforming. This durability ensures extended usage life and consistent grinding results.

Furthermore, zirconia microsphere grinding beads exhibit minimal wear loss, even under demanding grinding conditions. This low wear characteristic allows for prolonged usage and maintains the beads' shape and size, resulting in stable and precise grinding outcomes. Additionally, their high wear resistance reduces the risk of contamination, ensuring the purity and integrity of the ground materials.

Zirconia microsphere beads are specifically designed for grinding materials down to the nano size, enabling the production of finely ground particles with controlled size distributions. They are particularly suitable for applications involving electronic ceramics, ceramic ink, MLCC, CMP, and photo catalysts, where achieving precise particle sizes is critical for optimal performance.

In conclusion, zirconia microsphere grinding beads made from high-quality yttria-stabilized zirconia powder via the hydrolysis process offer exceptional grinding efficiency. Their high crushing strength, low wear loss, and adherence to international quality standards make them reliable and effective grinding media. These beads are well-suited for grinding materials to the nano size range in various industries, including electronic ceramics, ceramic ink, MLCC, CMP, and photo catalysts, ensuring precise and high-quality grinding results.
