Zirconium oxide grinding beads are high-precision ceramic media specially engineered for ultra-fine particle reduction and delicate surface polishing. Manufactured through advanced isostatic pressing and high-temperature sintering, these beads feature ultra-high sphericity, uniform density and extremely low surface roughness. Different from ordinary grinding media, they deliver gentle yet powerful shear and friction force, which effectively breaks material agglomerations, refines coarse particles to micron and submicron levels, and creates smooth, flawless surface finishes. With zero impurity shedding and stable physical properties, they fully meet strict standards for ultra-fine powder processing and high-precision polishing applications.

Their mirror-smooth spherical surface ensures uniform contact with materials, avoiding scratches and uneven grinding that commonly occur with low-quality media.
High hardness and toughness enable consistent ultra-fine grinding performance, steadily reducing particle size without causing excessive material damage.
The ultra-low wear rate prevents media contamination, ensuring high purity and uniformity of finished ultra-fine powders and polished workpieces.
Tailored for ultra-fine particle refinement and polishing work, the beads are widely used in high-precision industries:
Ideal for ultra-fine grinding of new energy battery materials, electronic ceramics, high-purity pigments, and cosmetic powders.
Excels in fine surface polishing of precision hardware, optical components, and ceramic parts, delivering ultra-smooth surface texture and dimensional accuracy.
They can stably process materials down to submicron and nano-level fineness, realizing uniform ultra-fine particle reduction.
Yes, the high-precision smooth surface provides soft and balanced grinding force without scratching or damaging workpieces.
Small sizes from 0.2mm to 1.5mm are the most suitable for ultra-fine grinding and precision polishing tasks.
They are composed of 95% Yttrium-stabilized Zirconium Oxide, manufactured via isostatic pressing and high-temperature sintering.
Their ultra-low wear rate, high Vickers hardness (1250–1350 HV), and zero impurity shedding prevent contamination during grinding.
They offer a bulk density of 6.0–6.15 g/cm³, G5 high precision grade, mirror-polished surface finish, and sizes ranging from 0.2mm to 6.0mm.
