Ceria Stab. Zirconia Beads — Product Overview

Technology: Sintering

Size: 0.4 – 15 mm

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 machines. Ceria stabilized zirconia grinding beads have the largest specific gravity among zirconia grinding media (5.5 ~ 6.20 g/cm³ based on customer needs). From a kinetic perspective (EC = ½mv²), using ceria stabilized zirconia grinding beads delivers greater impact energy, thereby enhancing production efficiency — especially for high viscosity or high-solid abrasive products. For low viscosity products, selecting smaller Ce-stabilized zirconia abrasive beads increases the grinding surface area per fixed volume, resulting in superior grinding performance.

Features

Micro-structure of delicate, uniform, dense ceramics of the highest quality — possessing gem-like hardness and density, making it the most outstanding among all zirconia grinding media series. Its excellent wear resistance and fracture toughness make it particularly suited for high-solid-phase, high-viscosity, and high-hardness paste grinding and dispersion; while also delivering superior compatibility with high-input-energy and high-shear sanding machines.

Frequently Asked Questions

Q What makes Ceria-Stabilized Zirconia Beads different from Yttria-Stabilized Zirconia Beads?
Ceria-Stabilized Zirconia (Ce-TZP) beads feature a higher specific density (5.95–6.2 g/cm³) compared to standard yttria-stabilized beads, resulting in greater kinetic impact energy during milling. This makes them especially advantageous for high-viscosity and high-solid-content applications. They also offer superior fracture toughness (8.5 MPa·m¹/²), reducing bead breakage and contamination risk.
Q What sizes are available for Ceria-Stabilized Zirconia Beads?
The beads are available in a wide range of spherical diameters: Φ0.4, Φ0.6, Φ1, Φ1.5, Φ2, Φ2.5, Φ3, Φ10, Φ12, and Φ15 mm. The appropriate size depends on your 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 wear rate and high chemical inertness, Ce-stabilized zirconia beads are well-suited for pharmaceutical active ingredient grinding, biotechnology applications, food processing, and cosmetics manufacturing — all areas where zero or near-zero contamination is essential.
Q What types of milling equipment are compatible with these beads?
Ceria-Stabilized Zirconia Beads are compatible with all types of high-shear energy bead mills and sand mills, including horizontal, vertical, and basket mill configurations. Their high hardness (HV > 9 GPa) and excellent fracture toughness ensure reliable performance even under intense milling conditions.
Q What is the composition of Ceria-Stabilized Zirconia Beads?
The beads are composed of 78–80% ZrO₂ and 13–20% CeO₂ by weight. This specific composition provides the optimal balance of high density, hardness, fracture toughness, and chemical stability required for demanding grinding and dispersion applications.
Q How do I select the right bead size for my application?
For high-viscosity or high-solid-content materials, larger beads (e.g., Φ2–Φ3 mm) are recommended to deliver greater impact energy. For low-viscosity materials or when a very fine final particle size is required, smaller beads (e.g., Φ0.4–Φ1 mm) are preferred, as they provide a larger total grinding surface area per unit volume, resulting in more efficient and finer grinding.
