Are media fractures and contamination slowing down your production? In the realm of nano-grade grinding, standard ceramic beads often fail to deliver consistent results. They break under stress or wear down too quickly, driving up costs.

Based on 15+ years of manufacturing expertise, Zhuzhou Chuangrui has developed the PR-ZR Yellow Zirconia Series—a breakthrough solution that addresses the core challenges of modern industrial grinding. Our proprietary Praseodymium-stabilized zirconia technology delivers unprecedented performance in both fracture toughness and wear resistance.

Designed for high-energy mills, our PR-ZR series ensures cleaner, faster, and more cost-effective processing for industries ranging from paints and inks to advanced battery materials. The distinctive yellow color provides instant visual identification, preventing cross-batch contamination in multi-product facilities.

Advanced Microstructure Engineering

The PR-ZR series utilizes a specialized two-stage sintering process that creates a uniform, fine-grained tetragonal phase structure. This microstructure optimization provides:

• Enhanced Fracture Toughness: K_IC ≥ 10 MPa·m^1/2
• High Vickers Hardness: HV ≥ 1250 kg/mm²
• Uniform Grain Size: 0.3-0.5μm average

Chemical Stability & Compatibility

PR-ZR beads maintain exceptional chemical inertness across a wide pH range, making them suitable for:

• Acidic environments (pH 2-7) for metal oxide dispersions
• Alkaline conditions (pH 7-12) for ceramic slurries
• Organic solvent systems in ink and coating production

Q: Will the yellow color fade or contaminate my product?

A: No. The yellow color is intrinsic to the Praseodymium element used in the crystal structure, not a surface coating or dye. It is chemically stable and will never fade or leach into your slurry.

Q: What types of mills are compatible?

A: PR-ZR beads are compatible with all modern grinding equipment, including horizontal sand mills, vertical mills, and basket mills. Their high toughness makes them ideal for high-speed pin-type mills.

Q: How does this compare to Ceria-stabilized Zirconia?

A: PR-ZR offers a more cost-effective solution with comparable density (6.0+ g/cm³). While Ce-TZP has slightly higher toughness, PR-ZR provides 90-95% of the performance at 40-50% lower cost, representing better value for most applications.

Q: What bead size range is available?

A: We offer sizes from 0.1mm to 3.0mm. For nano-grinding (<0.1μm D50), 0.1-0.3mm beads are recommended. Our technical team can help select the optimal size for your specific process.

Q: How is wear rate measured and guaranteed?

A: We conduct standardized 100-hour wear tests in lab-scale mills using reference materials. Typical wear rates are below 0.5% per 100 hours. All products come with documented test reports.

Q: What is your production time for bulk order?

A: The delivery time usually depends on the order quantity, around 7-30 Days.
