Zirconia Grinding Jar is a high-performance milling container used in ball mills, planetary ball mills, and other grinding equipment for mixing, homogenizing, and reducing particle size in various materials. Made from yttria-stabilized zirconia (YSZ), these jars are known for their exceptional hardness, wear resistance, and chemical inertness, making them ideal for demanding grinding applications.

Key Features & Specifications

1. Material Composition

• Primary Material: Yttria-stabilized zirconia (YSZ – typically 3% or 8% Y₂O₃)

• Density: ~6.0 g/cm³

• Hardness: ~9 on the Mohs scale (comparable to tungsten carbide)

• Flexural Strength: ~900-1200 MPa

• Fracture Toughness: High resistance to cracking

2. Design & Construction

• Shape: Cylindrical with a tight-sealing lid

• Available Sizes: Ranging from 50 mL to 1000 mL (common sizes: 100 mL, 250 mL, 500 mL)

• Lid Mechanism: O-ring sealed for airtight operation (prevents contamination)

• Grinding Media Compatibility: Works with zirconia, alumina, or stainless steel balls

3. Advantages

✅ Superior Wear Resistance – Minimizes contamination due to minimal abrasion.
✅ High Mechanical Strength – Withstands high-impact grinding conditions.
✅ Chemical Inertness – Resistant to acids, alkalis, and organic solvents.
✅ Low Contamination – Ideal for ultra-fine grinding of ceramics, pharmaceuticals, and electronic materials.
✅ Thermal Stability – Can endure high temperatures (up to 1000°C).

4. Applications

• Nanoparticle synthesis (e.g., ceramics, metal oxides)

• Pharmaceutical & biomedical research

• Battery materials processing (Li-ion, cathode/anode materials)

• Geology & mineralogy (sample preparation for XRF/XRD analysis)

• Food & cosmetics (fine powder homogenization)

5. Maintenance & Handling

• Cleaning: Use ultrasonic cleaners with mild detergents or dilute acids.

• Storage: Keep in a dry environment to prevent moisture absorption.

• Avoid: Sudden thermal shocks to prevent micro-cracks.
