ZrO2 grinding beads, also known as zirconia grinding media, are high-performance spherical grinding beads made from high-purity zirconia (ZrO2) with yttrium oxide as a stabilizer, through high-temperature sintering and precision shaping. Designed for ultra-fine grinding and dispersion of high-viscosity, high-hardness, and zero-contamination-required materials, these beads stand out for their exceptional hardness and wear resistance, making them an ideal choice for various industrial grinding applications that demand high efficiency and product purity.
| Item | Specification |
|---|---|
| Material | Tetragonal Zirconium Polycrystal (TZP) ZrO2 |
| Hardness (Mohs) | ≥ 9.0 |
| Density | 6.0-6.2 g/cm³ |
| Wear Loss | ≤ 0.01 ppm/h |
| Operating Temperature | ≤ 1000℃ |
| Particle Size | 0.1-10 mm (Customizable) |
With a Mohs hardness over 9.0, wear loss is as low as 0.01 ppm/h—30-50 times higher than glass beads and 5-10 times higher than alumina beads.
A high density of 6.0-6.2 g/cm³ significantly enhances grinding efficiency by increasing impact and shear force between beads and materials.
Non-toxic and highly corrosion-resistant to most acids and organic solvents, ensuring complete purity of the ground materials.
Exceptionally durable and reusable for multiple operational cycles, effectively reducing overall production costs and environmental impact.
Used for ultra-fine grinding of ground calcium carbonate for papermaking.
Ensures uniform dispersion of pigments and fillers to improve overall product quality.
Essential for high-precision grinding of electronic materials and lithium-ion battery electrode materials.
Ideal for magnetic materials, pharmaceutical, and food industries requiring strict purity control.
