Ceramic Grinding Media for Paints, Inks & Pigment Manufacturing
During the comminution process utilizing ceramic microbeads, dye particles or pigments are subjected to wet milling within a suspension or dispersion medium, achieving particle size reduction to the micrometer scale and, in part, to the nanometer range. Attainment of critical performance characteristics—such as opacity, chromatic intensity, luminance, and long-term stability—necessitates the production of nanoscale dye particles through high-energy milling techniques.

Our Supply Scope
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 Y-TZP Zirconia Beads 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.
