Product Details

Zirconia Beads Φ0.05-5.0 mm

• Zirconia Beads Φ0.05-5.0 mm offers a uniform bead size distribution and a low self-wear rate, so grinding results stay repeatable in ultra-fine grinding and dispersion of lithium battery materials, MLCC and electronic inks.

• The beads are chemically inert and non-contaminating, so the purity of the milled material is preserved and batch-to-batch consistency stays stable over a long service life.

• Available in a range of sizes and to customer drawings; batch quantities and tooling can be arranged on request.

1. Characteristics and Advantages of Zirconia Beads

• Zirconia Beads Φ0.05–5.0 mm offer uniform bead size distribution and a low self-wear rate, ensuring consistent grinding results in the ultra-fine grinding and dispersion of lithium battery materials, MLCC and electronic inks.

• Ultra-fine Grain Size: Finer raw materials, lower wear rates and longer service life.

• Ultra-high Density: An ultra-dense internal structure provides strong impact resistance and helps prevent bead breakage during use.

• Uniform Bead Size Distribution: Provides more stable grinding performance and consistent production results.

• Smooth Surface: Reduces self-wear during grinding.

2. Production Process of Chuangrui Zirconia Beads

• A unique extrusion molding process ensures uniform bead size and a dense structure.

• Hydrothermal nano raw materials and low-temperature sintering produce beads with smooth surfaces and excellent wear resistance.

• Three-stage selection and secondary screening ensure sphericity and uniform bead size distribution.

• Ultra-high-speed pre-grinding helps reduce the risk of bead breakage during use.

• Suitable for ultra-fine dispersion of various materials, including high-viscosity materials.

3. Applications

• Suitable for ultra-fine grinding and dispersion of various materials, including lithium iron phosphate cathode materials, silicon-carbon anode materials, electronic materials, magnetic materials and carbon nanotubes. Also suitable for high-viscosity applications.
