Our company’s ZR95 Nano zirconia beads, also known as zirconia ceramic beads, are primarily composed of zirconium dioxide (ZrO₂) and yttrium oxide (ZrO₂ + Y₂O₃ (stabilizer)), with a zirconium oxide content of approximately 94-95%. They are spherical or near-spherical ceramic particles manufactured using a special process. They are mainly used for micron- or nano-scale grinding and dispersion of materials requiring “zero pollution,” high viscosity, and high hardness. They are most commonly found in wet grinding equipment, such as sand mills and bead mills.
Application：
- Coating
- Cosmetic
- Electronic paste

Our ZR95 nano zirconia beads are manufactured using a unique extrusion molding process and selected ultrafine, high-purity, and fine-grained raw materials. This helps improve the purity and fineness of products used in both wet and dry grinding processes, particularly for materials requiring a nano-particle size range, where the effect is most pronounced.
The ZR95 nano zirconia beads are uniformly dense. Our manufacturers use a hydrothermal method with nanomaterials and a low-temperature sintering process to achieve a smoother surface. Experiments show that our beads exhibit exceptionally high wear resistance, far surpassing similar products.
After manufacturing, the beads undergo a three-stage selection and two-stage screening process to ensure the sphericity and particle size distribution of the zirconia beads from the outset. Each batch of beads is randomly sampled by the quality control department, and engineers use ultra-high-speed pre-grinding to ensure no broken beads during use.
These zirconia beads are made from micron- to nano-sized raw materials and sintered at low temperatures to achieve an extremely smooth surface, like a pearl, while possessing a hardness second only to diamond. Our zirconia beads undergo multiple layers of screening to strictly ensure shape stability and particle size distribution. Multiple ultra-high-speed grinding tests verify their true durability and performance, ensuring no bead breakage occurs during grinding.

Guidelines for ZR95 Zirconia Beads
ZR95 zirconia beads, also known as high-purity Yttria-stabilized zirconia beads or high-purity tetragonal phase zirconia polycrystalline beads, offer significantly superior grinding performance compared to other products on the market, such as zirconium silicate beads, zirconia composite beads, and cerium-stabilized zirconia beads. They can be used in sand mills from ultra-large Φ5-10mm (for coarse grinding or high-capacity mills) to extremely fine Φ0.03-0.1mm (30-100µm, for nanoscale ultrafine grinding).
Application Scenarios of ZR95 Nano Zirconia Beads
ZR95 zirconia beads are also called nano-sized yttrium-stabilized zirconia microspheres. The zirconium oxide content reaches ≥94.5%, and we offer ceramic beads with oxygen contents of 2% and 5% as options. Their density can reach ≥6.0 g/cm³, and their particle size ranges from Φ0.05 to Φ2.0 mm. Through numerous experiments in grinding equipment, their wear rate is ᐸ 200 ppm/h. Our company’s ZR95 zirconia beads are characterized by high hardness, high toughness, high wear resistance, and low pollution. Most of our customers are concentrated in the fields of electronic pastes, electronic ceramics, high-end pigments, inks, pharmaceuticals, cosmetics, and pesticides:
1. New Energy Battery Applications: Nanoscale grinding of positive and negative electrode materials such as lithium iron phosphate (LFP) and ternary materials (NCM/NCA). Even the slightest contamination can affect battery performance and safety.
2. Electronic Ceramics Applications: MLCC dielectrics, magnetic materials, phosphors, etc. Impurities can severely degrade dielectric, magnetic, or luminescent properties.
3. High-End Pigment/Ink Applications: Automotive paints, high-end digital inkjet printing, requiring pure colors and uniform dispersion.
4. Pharmaceutical/Cosmetic/Food Additive Applications: Strict regulations regarding foreign matter and heavy metal residues.
5. Pesticide Nanoscale Applications: Requires an extremely fine and stable suspension system.
