Zirconia Beads
Product Information
Zirconia beads are a high-performance grinding medium, mainly made of micron- and sub-nano-level zirconium oxide and yttrium oxide. It is mainly used for ultra-fine grinding and dispersion of materials that require "zero pollution" and high viscosity and high hardness. It is widely used in electronic ceramics, magnetic materials, zirconium oxide, silicon oxide, zirconium silicate, titanium dioxide, pharmaceutical food, pigments, dyes, inks, special chemical industries and other fields.
Features:
High density: The density of zirconia beads is 6.0g/cm³, which has extremely high grinding efficiency and can increase the solid content of materials or increase the flow rate of materials.
High toughness: It is not easy to break during high-speed operation, and its wear resistance is 30-50 times that of glass beads.
Low pollution: It is suitable for occasions requiring "zero pollution" because its material will not cause pollution to the material.
High temperature and corrosion resistance: The strength and hardness are almost unchanged at 600℃, which is suitable for grinding operations in high temperature environments.
Good sphericity and surface smoothness: The sphere has good overall roundness, smooth surface, and pearl-like luster, suitable for various grinding equipment.
Details Images
The size of zirconia beads ranges from 0.05mm to 50mm. Common sizes include 0.1-0.2mm, 0.2-0.3mm, 0.3-0.4mm, 0.4-0.6mm, 0.6-0.8mm, 0.8-1.0mm, 1.8-2.0mm, etc., suitable for different grinding needs.
Fine grinding: Smaller zirconia beads (such as 0.1-0.2mm) are suitable for fine grinding, such as grinding of electronic materials or nanomaterials.
Ordinary grinding: Medium zirconia beads (such as 0.4-0.6mm, 0.6-0.8mm) are suitable for grinding ordinary materials, such as coatings, paints, etc.
Bulk material grinding: Larger zirconia beads (such as 10mm, 12mm) are suitable for grinding large and hard materials.
