Product Overview
Zirconia Media are high-performance ceramic grinding and polishing media manufactured from high-purity zirconium oxide (ZrO₂). With their exceptional density, outstanding wear resistance, and chemical inertness, zirconia media have established themselves as the benchmark product in high-end surface finishing and ultra-fine grinding applications.
Compared to traditional glass beads or zirconium silicate media, zirconia media offer significantly higher grinding efficiency and wear resistance-30 to 50 times that of glass beads-while virtually eliminating product contamination. Whether in high-speed stirred mills or vibratory finishing equipment, they deliver unmatched performance.
Core Material & Stabilization System
Yttria-Stabilized Zirconia (Y-TZP)
Yttria-Stabilized Zirconia represents the highest grade of zirconia media available. By adding approximately 5% yttrium oxide (Y₂O₃) for stabilization, the media achieves optimal mechanical properties and wear resistance.
Key Advantages:
High Density (True Density ~6.0 g/cm³)
Superior grinding efficiency and energy transfer
High Hardness (Vickers Hardness ~1250 HV)
Suitable for grinding extremely hard materials
High Fracture Toughness
Excellent resistance to cracking even under high-speed operation
Chemical Inertness
No reaction with milled materials, ensuring product purity
Key Features
Superior Grinding Efficiency
The high density of zirconia media enables more efficient energy transfer to the milled material, resulting in faster and finer particle size reduction while saving grinding time and energy consumption.
Ultra-Low Contamination
Exceptional wear resistance means minimal media wear, significantly reducing the risk of cross-contamination of milled materials-critical for high-purity applications in electronics, pharmaceuticals, and food industries.
Excellent Sphericity & Size Distribution
Tightly controlled sphericity and particle size distribution ensure uniform grinding results and precise control over final product quality.
High Temperature & Corrosion Resistance
Suitable for high-temperature grinding processes and resistant to corrosive environments including acids and alkalis.
