Specific Density: 5.95 – 6.2 g/cm³

Bulk Density: 3.9 g/ml

Hardness: 1200 HV1

Intensity of high hardness, wear resistance, and applicable to all types of high shear energy sanding machine.

Ceria stabilized zirconia grinding beads offer the highest specific density in the zirconia grinding media series (5.5 ~ 6.20 g/cm³, based on customer requirements). From a dynamics perspective (EC = ½mv²), using ceria-stabilized zirconia grinding media generates greater impact energy, thereby enhancing production efficiency — especially for high-viscosity or high-solid abrasive products. For low-viscosity products, the smaller bead size option increases the grinding surface area, delivering even better grinding results.

Frequently Asked Questions (FAQ)
Q What makes Ceria-Stabilized Zirconia Beads different from Yttria-Stabilized Zirconia Beads?
Ceria-Stabilized Zirconia (Ce-TZP) beads offer a higher specific density (up to 6.2 g/cm³) compared to Yttria-Stabilized Zirconia (Y-TZP), which typically reaches around 6.0 g/cm³. The higher density of Ce-TZP generates greater kinetic impact energy during milling, making it especially advantageous for grinding high-viscosity and high-solid-content materials. Ce-TZP also exhibits superior fracture toughness, reducing bead breakage in demanding applications.
Q What bead sizes are available for Ceria-Stabilized Zirconia Beads?
Ceria-Stabilized Zirconia Beads are available in a wide range of sphere diameters: Φ0.4, Φ0.6, Φ1, Φ1.5, Φ2, Φ2.5, Φ3, Φ10, Φ12, and Φ15 mm. The appropriate size depends on the target particle size, material viscosity, and the type of milling equipment used.
Q Are Ceria-Stabilized Zirconia Beads suitable for pharmaceutical and food-grade applications?
Yes. Due to their extremely low contamination rate and high chemical inertness, Ceria-Stabilized Zirconia Beads are well-suited for pharmaceutical active ingredient wet grinding, biotechnology applications, food processing, and cosmetics manufacturing — industries where product purity and zero contamination are critical requirements.
Q What types of milling equipment are compatible with these beads?
Ceria-Stabilized Zirconia Beads are compatible with all types of high-shear energy sanding and bead milling machines, including horizontal bead mills, vertical bead mills, basket mills, and attritor mills. Their high hardness (HV >1200) and fracture toughness (8.5 MPa·m¹/²) ensure reliable performance even under intense mechanical stress.
Q How does bead size selection affect grinding efficiency?
For high-viscosity or high-solid-content materials, larger bead sizes are recommended as they generate greater impact energy (EC = ½mv²), improving grinding efficiency. For low-viscosity materials or when finer particle sizes are required, smaller beads are preferred because they provide a larger total grinding surface area per unit volume, resulting in more uniform and efficient particle size reduction.
Q What is the typical composition of Ceria-Stabilized Zirconia Beads?
The beads consist of 78–80% ZrO₂ (Zirconia) and 13–20% CeO₂ (Ceria) by weight. This composition provides the optimal balance of high density, hardness, fracture toughness, and chemical stability required for demanding industrial grinding and dispersion applications.
