Product Description
0.4mm-3.0mm Polished Silicon Nitride (Si3N4) Grinding Media Balls
Polished Silicon Nitride Grinding Media Balls
Silicon nitride grinding media balls have desirable characteristics such as high strength, good wear/corrosion resistance, high temperature resistance, electrical insulation and are non-magnetic. Compared with other grinding media, it has a lighter weight (60% less than steel), lower thermal expansion, and reduced total operational cost. Its high hardness can meet the demands of a vast majority of metal powder crushing and refining. It is an ideal grinding media when high hardness, low contamination and less abrasion are required. Our silicon nitride media is available in sizes ranging from 0.4mm - 3.0mm, with other sizes available upon request.
Key Properties & Advantages
■ Hardness: Measures at 75–80 HRC, providing the ability to crush and refine incredibly hard metal powders and advanced ceramics.
■ Low Contamination: Significantly lower wear and reduction rates compared to zirconia or alumina balls, ensuring high purity.
■ Density: 3.2 g/cm³, which makes them roughly 40-50% lighter than standard bearing steel, reducing the load on machinery.
■ Thermal & Chemical Stability: Highly resistant to corrosion and capable of handling maximum operating temperatures up to 1000℃.
■ Electrical/Magnetic: Non-magnetic and electrically insulating, ideal for sensitive electronic and semiconductor applications.
Common Applications
Semiconductors: Glass frit pulverization and specialized powder processing.
Advanced Materials: Fine grinding and dispersion of high-strength non-oxide ceramics and electronic coatings.
High-Purity Chemicals: Applications where contamination from metallic wear debris must be strictly avoided.
