Composite Zirconia Bead Description
Composite Zirconia Beads are made from high-quality zirconia and alumina raw materials through a process that involves titration rolling into blanks and high-temperature sintering for phase formation. The beads consist of uniformly toughened zirconia grains, which enhance their hardness and reduce the formation of irregularly shaped beads. The excellent sphericity and medium-to-high density of the beads improve grinding efficiency. In many applications, this product serves as a cost-effective alternative to pure zirconia beads.

FAQs
Q1. What are Composite Zirconia Beads?
Composite zirconia beads are advanced ceramic grinding media made from a combination of zirconia, alumina, and yttria. They are known for their high density, wear resistance, and excellent mechanical strength, making them ideal for high-energy milling processes.
Q2. What are the main components of these beads?
These beads are primarily composed of zirconia (ZrO₂), with alumina (Al₂O₃) and yttria (Y₂O₃) added to enhance their properties. Yttria is often used as a stabilizer for zirconia to improve its durability and mechanical performance.
Q3. What are the key advantages of using Composite Zirconia Beads?
- High Density: Offers efficient grinding and reduces milling time.
- Excellent Wear Resistance: Minimizes contamination of the milled material and extends the life of the grinding media.
- High Fracture Toughness: Resists cracking and breaking under high-stress conditions.
- Chemical Stability: Resistant to acids, alkalis, and other corrosive environments.
