The Zirconia Grinding Ball, specifically Yttria Stabilized Zirconia (YSZ), represents the highest standard of ceramic milling media. Manufactured from sub-micron and nano-scale zirconia powder, these beads exhibit a perfectly spherical shape and a dense, flawless internal structure. Due to their exceptional specific gravity, they generate massive impact energy in high-speed mills, enabling highly efficient dispersion and ultra-fine, nano-level grinding of advanced materials.
Exhibits a wear rate at the parts-per-million (ppm) level, ensuring prolonged media life and absolute zero contamination for high-purity materials.
With a density exceeding 6.0 g/cm³, it provides maximum kinetic energy, drastically increasing grinding efficiency and reducing processing time.
Highly resilient against impact and friction, ensuring the beads will not shatter or break even in high-speed, high-energy agitation mills.
Highly inert and resistant to corrosion from acids, alkalis, and solvents, suitable for various wet and dry chemical milling processes.
The perfectly polished, spherical surface significantly reduces internal friction and minimizes wear on mill linings and equipment parts.

They are manufactured from high-purity sub-micron and nano-scale zirconia powder with a ZrO2 content equal to or exceeding 95%, stabilized with yttria for superior structural integrity.
With a density greater than 6.0 g/cm³, these beads produce substantially higher kinetic impact energy in agitation and pearl mills, significantly accelerating dispersion and shortening milling cycles.
The beads demonstrate an ultra-low wear loss of ≤ 0.002%, minimizing media replenishment costs and ensuring zero contamination in sensitive, high-purity applications.
Yes. YSZ beads possess exceptional chemical stability and are inert to strong acids, alkaline substances, and organic solvents used in both wet and dry processing.
Due to their outstanding fracture toughness (≥ 8.0 MPa·m½) and perfectly smooth spheroidized surface, they are ideal for high-speed sand mills, bead mills, horizontal attrition mills, and planetary ball mills without damaging inner liners.
Standard sizes range from φ0.5 mm and φ1.0 mm for fine nano-milling up to φ50 mm for larger coarse dispersion systems.
