Wear-Resistant Silicon Nitride Balls Process Characteristics
1. Unique Extrusion Molding Process: Ensures uniform and dense green bodies.
2. Vacuum Sintering: Achieves a density of ≥3.2g/cm³.
3. Ultra High Abrasion Resistance: Over 10 times more wear-resistant than zirconia beads and nearly 20 times more than high-purity zirconia beads, offering an excellent cost-performance ratio.
4. Higher Actual Linear Speed: Effectively increases the efficiency of ultra-fine dispersion by over 30%.
5. Density Only 53% of Zirconia Beads: Can reduce energy consumption and heat generation during the ultra-fine grinding process.
6. Extremely Low Wear Rate: Significantly reduces the frequency of adding and replacing grinding media, ensuring the stability of the production system.
7. Application: Suitable for ultra-fine dispersion of high-end materials, especially under conditions with extremely high purity and fineness requirements.
