Detailed Specifications & Features
1. Brand: ZOLI
Assured Quality: The ZOLI brand represents a commitment to precision manufacturing and quality control, ensuring consistent performance and reliability.
Trusted Specifications: Products from a defined brand often come with more reliable dimensional accuracy and material certification, which is critical for mill compatibility and experimental reproducibility.
2. Capacity: 1000 ml (1 Liter)
Versatile Workhorse: The 1L size strikes a perfect balance, offering a substantial volume for processing meaningful batch sizes while remaining manageable for most mid-to-large-sized laboratory planetary mills.
Ideal For:
- Pilot-Scale Studies: Bridging the gap between small-scale R&D (50-500ml) and full production.
- Material Synthesis: Producing sufficient quantities of nano-powders, composites, or mechanical alloys for further testing and characterization.
- Batch Processing: Creating larger volumes of specialized materials like battery electrodes, advanced ceramics, or pharmaceutical intermediates.
3. Material: Yttria-Stabilized Zirconia (YSZ)
This is the core of the jar's premium performance:
- Unmatched Wear Resistance: Zirconia is exceptionally hard (≥ 9 on the Mohs scale), ensuring minimal wear from the grinding balls and the sample material. This translates to a long service life and stable performance over time.
- Extreme Contamination Control: YSZ is chemically inert and possesses a very low abrasion rate. This guarantees that your sample remains pure, with negligible ionic contamination from the jar itself, which is critical for electronic, catalytic, and high-purity ceramic applications.
- Superior Fracture Toughness: The addition of Yttria (Y₂O₃) stabilizes the zirconia crystal structure, preventing a destructive phase transition during heating/cooling and giving the material remarkable resistance to chipping and mechanical shock—a significant advantage over other ceramics like Alumina.
- High Density: The high density of zirconia (∼6.0 g/cm³) enhances the impact energy of the grinding balls, leading to more efficient milling and shorter processing times.
- Excellent Corrosion Resistance: Highly resistant to a wide range of acids, alkalis, and organic solvents, making it perfectly suited for both dry and wet milling processes.
4. Design and Construction:
- Precision Engineering: The jar is manufactured to precise tolerances to ensure a perfect fit on compatible planetary mill stations.
- Leak-Proof Seal: Features a robust sealing lid with a high-quality, chemically resistant O-ring (typically Viton or NBR) to securely contain powders, slurries, and inert gas atmospheres during milling.
- Optimized Internal Geometry: The smooth, internal contours facilitate efficient movement of the grinding balls and easy cleaning, minimizing dead zones and cross-contamination.
Typical Applications
This jar is utilized across a wide spectrum of high-tech industries and research fields:
- Advanced Materials Science: Mechanical alloying, synthesis of nanocomposites, and production of amorphous metals.
- Electronics & Battery Research: Grinding and homogenizing of cathode/anode materials (e.g., NMC, LFP), solid electrolytes, and functional ceramics for capacitors and sensors.
- Pharmaceuticals: Size reduction of active pharmaceutical ingredients (APIs) to enhance bioavailability and uniform blending of drug compounds.
- Geology & Mining: Pulverizing rock and mineral samples to a fine homogenized powder for accurate XRF, XRD, or ICP-MS analysis.
- Chemicals & Pigments: Developing highly dispersed pigments and facilitating mechanochemical reactions.
Critical Considerations Before Purchase
Mill Compatibility (Most Important):
You MUST verify that your specific planetary ball mill (e.g., Retsch PM 100/200/400, Fritsch Pulverisette 5/6/7, or MTI, Across International models) can accommodate a 1L jar.
Check the manufacturer's specifications for the maximum allowable jar volume, weight, and dimensional constraints (outer diameter and height).
Grinding Media:
You must use grinding balls made of the same material—Yttria-Stabilized Zirconia.
Using a different, harder material (like tungsten carbide) will rapidly damage the jar's interior. Select an appropriate mix of ball sizes (e.g., 5mm, 10mm) for optimal milling efficiency.
Operating Guidelines:
Filling Ratio: Never fill the jar more than one-third to one-half of its total volume with grinding balls and material. Overfilling prevents the cascading motion necessary for effective grinding.
Speed and Time: Follow optimal milling parameters for your material. Excessive speed can generate too much heat and stress on the jar.
Care and Maintenance:
Clean thoroughly after each use with appropriate solvents (e.g., water, ethanol) and/or an ultrasonic cleaner.
Inspect the jar and O-ring regularly for signs of wear or damage. A compromised seal will lead to sample loss and potential contamination.
