Introduction to 
Zirconia Media
• Zirconia grinding media are 
advanced ceramic beads used in 
high-energy milling, dispersion, 
and grinding applications.
Known for:
• High hardness and toughness
• Superior wear resistance
• Minimal contamination during 
milling
Used in: coatings, pharmaceuticals, 
pigments, and nanomaterial 
processing.
Why Media Selection 
Matters
Choosing the right zirconia milling beads ensures:
• Consistent particle size reduction
• Maximum energy transfer during milling
• Lower contamination and media wear
• Improved product uniformity and dispersion quality

Selecting the Right Media 
Size
• Smaller zirconia grinding beads → higher surface 
area, finer results
• Larger zirconia milling beads → better impact for 
coarse grinding
Application Recommended Size Key Advantage
Fine milling & Uniform nano-size 
dispersion 0.1 – 0.5 mm particles
Medium grinding 0.5 – 2 mm Balanced energy & 
efficiency
Coarse milling 2 – 10 mm High impact strength
Role of Media Density
• Density affects kinetic energy and grinding 
performance:
• High-density zirconia milling media: best for hard 
materials and fast processing
• Low-density media: suitable for soft materials or gentle 
dispersion
• Common densities: 5.9–6.1 g/cm³ for YSZ grinding 
media
Understanding Stabilizer 
Types
• YSZ milling media is most common due to excellent 
toughness and chemical resistance.
Stabilizer Description Typical Use

Tips for Optimal 
Performance
• Match bead size to mill type and viscosity.
• Choose YSZ milling media for aggressive grinding or 
high-wear environments.
• Avoid mixing old and new media — causes uneven wear.
• Regularly monitor bead wear and contamination levels.
Cost vs. Performance 
Consideration
• Although zirconia grinding media have a higher initial 
cost, their:
• Long lifespan
• High wear resistance
• Low contamination risk
 make them more cost-effective over time compared to 
alumina or glass beads.
Conclusion
• The right choice of zirconia milling media depends on:
• Particle size goal
• Material hardness
• Milling environment
• Stabilizer chemistry (YSZ or Ceria)
• YSZ grinding media remains the industry standard for 
consistent, high-performance results.
