Yttria-Stabilized Zirconia (YSZ) Grinding Jar – Premium Product Description

Ultra-Precision Milling Solution for Demanding Applications

Technical Superiority

• Material Composition: 3mol% or 5mol% yttria-stabilized zirconia (3YSZ/5YSZ)
• Crystal Structure: Fully stabilized cubic phase for maximum fracture toughness
• Density: ≥6.05 g/cm³ (near-theoretical density)
• Hardness: 1,200-1,300 HV (Vickers)
• Fracture Toughness: 5-7 MPa·m¹/² (superior to alumina)

Unmatched Performance Characteristics

1. Extreme Wear Resistance

   • 15-20× longer service life than alumina counterparts

   • <0.01% weight loss after 500 hours continuous milling

   • Ideal for processing hard materials (SiC, WC, Al₂O₃)

2. Absolute Chemical Purity

   • 99.95% purity grade available

   • <1ppm metallic contamination

   • USP Class VI compliant for pharmaceutical applications

3. Thermal Stability

   • Continuous use up to 800°C

   • Peak resistance to 1,550°C

   • Near-zero thermal expansion (10.5×10⁻⁶/°C)

Precision Engineering Features

• Dimensional Accuracy: ±0.1mm tolerance on critical surfaces

• Surface Finish Options:

  • Standard: Ra 0.4μm (mirror polished)

  • Enhanced: Ra 0.1μm (ultra-smooth for minimal adhesion)

  • Textured: Custom patterns for optimized grinding efficiency

• Sealing Systems:

  • Triple-seal PTFE gasket design

  • Gas-tight metal clamp options

  • Custom vacuum/inert gas ports
