Frequently Asked Questions (FAQ)
Q
What is Yttria Stabilized Zirconia (YSZ) and why is it used for grinding beads?
Yttria Stabilized Zirconia (YSZ) is a zirconia ceramic stabilized with yttrium oxide (Y₂O₃), typically at 5.25 wt%. This stabilization greatly enhances toughness, hardness, and wear resistance, making YSZ beads ideal for high-efficiency grinding and dispersion with minimal contamination of the processed material.
Q
What sizes of Zirconia Ceramic Beads are available?
Zirconia ceramic beads are available in a wide range of sizes from Φ0.1 mm up to Φ55 mm, covering ultra-fine nano-grinding to large-scale milling applications. Custom sizes can also be accommodated upon request.
Q
How do Zirconia Beads compare to other grinding media in terms of wear resistance?
Zirconia beads significantly outperform traditional grinding media such as glass beads, alumina beads, and steel balls in wear resistance. Their extremely low wear rate reduces product contamination and extends media service life, resulting in lower overall operating costs.
Q
Are Zirconia Ceramic Beads suitable for pharmaceutical and food applications?
Yes. Due to their high purity composition (94.5% ZrO₂ + 5.25% Y₂O₃) and extremely low wear rate, zirconia beads are safe for use in pharmaceutical ingredient processing, health supplement manufacturing, and food-grade milling applications where contamination control is critical.
Q
What is the specific density and hardness of these Zirconia Beads?
The specific density of these zirconia beads is ≥6.02 g/cm³, and the Vickers hardness exceeds 8.5 GPa. These properties ensure high grinding efficiency and excellent durability even under intensive milling conditions.
Q
Which industries benefit most from using Zirconia Ceramic Beads?
Zirconia ceramic beads are widely used across paints & coatings, inks, battery materials (lithium-ion), minerals & mining, agrochemicals, pharmaceuticals, food processing, electronics, structural ceramics, magnetic materials, metallurgy, cosmetics, textiles, and pigment industries — anywhere precise grinding and dispersion are required.
