Ceramic Grinding Media for Battery & Energy Materials Manufacturing

In battery manufacturing, especially for lithium-ion and advanced energy storage systems, grinding and dispersion are critical for creating homogenous cathode and anode slurries. Proper particle size and distribution directly influence the electrochemical performance, safety, and lifespan of batteries. Zirconium dioxide beads deliver powerful, consistent milling action to achieve nano-scale powders with uniform morphology. Stone Peak’s premium zirconia beads ensure stable grinding efficiency, minimal wear, and contamination control, enabling battery makers to produce high-performance materials that meet stringent energy density and quality demands.

Nano Zirconia Beads (Φ0.05-Φ2.0mm)

​

Nano yttria-stabilized zirconia beads are high-purity, ultrafine ceramic grinding media produced via a proprietary extrusion molding process. They exhibit uniform particle size, ultra-high density, and a smooth surface, resulting in exceptional wear and impact resistance. These properties ensure stable milling, consistent particle size distribution, and extended service life. Their biocompatibility minimizes contamination, preserving material purity—ideal for nanoscale grinding in applications such as energy storage materials, battery electrodes, and electronic components.

High Purity Zirconia Beads (Φ0.1-Φ5.0mm)

​

High-purity yttria-stabilized zirconium balls are precision-engineered ceramic grinding media characterized by uniform particle size, smooth surface, and excellent wear and impact resistance, ensuring extended operational life. Their biocompatibility minimizes contamination, making them ideal for high-purity applications in paints, textile and plastic dyes, pharmaceuticals, cosmetics, and battery materials.

Silicon Nitride Beads (Φ0.1-2.0mm)

​

Nitride Microbeads are ultra-wear-resistant ceramic media produced via proprietary extrusion molding and vacuum sintering. With a density >= 3.2 g/cm³, they exhibit wear resistance over 10× that of nano-zirconia and nearly 20× that of high-purity zirconia beads. Their minimal wear rate (~1 ppm over 24 hours) ensures low media consumption and minimal contamination, making them ideal for ultra-fine dispersion of high-purity, high-end materials under stringent processing conditions.
