Key Applications
These ZrO2 grinding beads excel in ultra fine particle size reduction and polishing across multiple high-demand industries. In the new energy sector, they are widely used for grinding lithium battery positive and negative materials (such as NCM and silicon-based anodes), achieving particle sizes as fine as sub-micron level to ensure battery performance stability. In the electronic materials field, they are applied to polish MLCC ceramic powders and sapphire substrates, meeting the strict requirements for purity and particle uniformity. Additionally, they are suitable for ultra fine grinding and polishing of pharmaceutical intermediates, food additives, and high-end pigments, ensuring zero contamination and consistent product quality.
Core Advantages
Compared with traditional grinding media, ZrO2 grinding beads offer distinct advantages. Their high hardness (Mohs 8.5) and high density enable efficient particle reduction, shortening grinding time by 30%-50% while achieving ultra fine particle sizes (D50 <1μm). The extremely low wear rate minimizes material contamination, which is critical for sensitive industries like electronics and pharmaceuticals. With excellent chemical stability and non-magnetic properties, they resist corrosion from various solvents and do not react with processed materials. Their smooth surface and high roundness also reduce wear on grinding equipment, extending equipment service life and lowering comprehensive operating costs.
