99.5% Al₂O₃ Ceramic Balls – The Ultimate Solution for High-Performance Grinding and Industrial Applications

99.5% alumina (Al₂O₃) ceramic balls are premium-grade grinding media and industrial filler materials known for their exceptional hardness, wear resistance, and chemical stability. With near-purity composition, these advanced ceramic balls outperform standard alumina products in demanding applications across industries like mining, electronics, and pharmaceuticals.

Key Properties of 99.5% Al₂O₃ Ceramic Balls

1.Superior Hardness

Mohs Hardness: 9 (equivalent to natural corundum/sapphire).

Vickers Hardness: 1,800–2,000 HV, ideal for grinding ultra-hard materials (e.g., silicon carbide, tungsten carbide).

2.Unmatched Wear Resistance

Abrasion loss: ≤0.05%/100 hours (vs. 0.1–0.5% for 95% Al₂O₃).

Lifespan 2–3× longer than lower-purity alumina balls.

3.Chemical Inertness

Resists acids/alkalis (pH 1–14), ensuring zero contamination in food/pharma applications.

Na₂O content <0.05%, preventing material degradation.

4.Thermal Stability

Withstands temperatures up to 1,750°C, suitable for high-heat processes.


Manufacturing Excellence

Raw Materials: High-purity α-Al₂O₃ powder (D50 <1µm).

Sintering: HIP (Hot Isostatic Pressing) at 1,600°C for zero porosity.

Quality Control: Laser-scanned sphericity (>95%), ISO 9001 certified.

Why Choose 99.5% Over 95% Al₂O₃?

50% lower wear rate in abrasive environments.

30% higher grinding efficiency due to denser structure.

Critical for precision applications (e.g., LED/LCD glass substrates).


Technical Specifications

Al₂O₃ Content: ≥99.5%

Apparent Particle Density: ≥3.63 g/cm³

Hardness, Mohs: 9

Available Sizes: 3mm–50mm


Conclusion

99.5% Al₂O₃ ceramic balls represent the pinnacle of grinding media technology, delivering unmatched durability and performance for mission-critical industrial processes. Whether for ultrafine powder production or harsh chemical environments, their near-theoretical purity ensures long-term cost savings and consistent quality.
