Wear Resistance Compared with Other Grinding Media
Frequently Asked Questions (FAQ)
❓ What are zirconia ceramic beads made of?
Zirconia ceramic beads are primarily composed of 94.5% ZrO₂ (zirconium dioxide) stabilized with 5.25% Y₂O₃ (yttrium oxide). This yttria-stabilized composition provides exceptional hardness, toughness, and wear resistance.
❓ What industries use zirconia ceramic beads?
Zirconia ceramic beads are widely used across numerous industries including paints & coatings, inks, battery materials, minerals & mining, agrochemicals, pharmaceuticals, food processing, electronic materials, cosmetics, textiles, and pigment manufacturing.
❓ What sizes are available for zirconia ceramic beads?
Zirconia ceramic beads are available in a wide range of sizes from Φ0.1 mm up to Φ55 mm, covering micro-grinding to large-scale milling applications. Custom sizes can also be discussed based on specific process requirements.
❓ Why choose yttria-stabilized zirconia beads over other grinding media?
Yttria-stabilized zirconia beads offer an extremely low wear rate, which prevents product contamination, delivers higher grinding efficiency, and significantly reduces total operational costs due to their extended service life compared to glass or alumina beads.
❓ Are zirconia ceramic beads suitable for pharmaceutical and food applications?
Yes. Due to their high purity, extremely low contamination rate, and chemical inertness, zirconia ceramic beads are ideal for grinding and homogenizing pharmaceutical ingredients, health supplements, and food products where strict purity standards must be maintained.
❓ What is the hardness and density of zirconia ceramic beads?
Zirconia ceramic beads have a Vickers hardness greater than 8.5 GPa and a specific density of ≥6.02 g/cm³. These properties make them one of the most durable and efficient grinding media available on the market.
