High-purity yttrium stabilized ZrO2 balls are professional ceramic grinding media customized for material precision refinement and ultra-smooth surface polishing. Manufactured via isostatic pressing and high-temperature sintering, these beads feature high sphericity, compact internal structure and stable chemical inertness. They deliver balanced shear and impact force during long-cycle grinding operations, efficiently disperse particle agglomerates and realize nano-scale refinement. With ultra-low self-wear rate and anti-cracking performance, they avoid impurity contamination, fully satisfying strict precision processing standards for industrial fine powder and workpiece surface finishing.

These ZrO2 balls own irreplaceable strengths in precision refinement and surface polishing. Higher density brings stronger grinding kinetic energy to shorten refinement cycles and narrow particle size distribution. Mirror-smooth spherical surface provides soft uniform contact pressure, eliminating scratches, pits and uneven texture on polished surfaces. Excellent mechanical toughness resists fragmentation under high-speed operation, extending service life and lowering overall production costs for high-precision manufacturing lines.
Matching the demand of precision refinement and surface polishing, ZrO2 balls are widely adopted across high-end industries. They perform outstandingly in ultra-fine grinding of lithium battery materials, electronic ceramic powder, high-purity pigments and nano coating slurries. Meanwhile, they serve as ideal polishing media for optical parts, precision hardware and ceramic components, compatible with sand mills, planetary ball mills and various lab & industrial grinding equipment.
Higher density, lower wear and smoother surface achieve finer particle refinement and scratch-free polished surfaces without introducing foreign impurities.
Yes, stable chemical and physical properties support both wet slurry dispersion and dry ultra-fine grinding & surface polishing processes.
They consist of 95% Yttrium-stabilized Zirconia, featuring a bulk density of 6.0–6.15 g/cm³, Vickers hardness of 1250–1350 HV, sphericity ≥98%, available sizes from 0.2mm to 10mm, and a mirror-polished surface finish.
They excel in the ultra-fine grinding of lithium battery materials, electronic ceramic powder, high-purity pigments, and nano coating slurries, as well as surface polishing for optical parts, precision hardware, and ceramic components.
Their high kinetic energy shortens grinding cycles, while excellent mechanical toughness and ultra-low self-wear rates prevent fragmentation and contamination, extending service life and reducing overall operational expenses.
They are fully compatible with sand mills, planetary ball mills, and a wide variety of laboratory and industrial grinding equipment.
