1. Core Material & Properties
Material: High-Purity Yttria-Stabilized Zirconia (YSZ), typically
95% ZrO₂ + 5% Y₂O₃.
Key Properties:
- Superlative Wear Resistance: The hardest and most wear-resistant
material available for mill jars. This property is paramount for
maintaining consistent results and achieving nano-scale grinds
without introducing coarse particles from jar wear.
- Extreme Heat Resistance: Withstands temperatures far exceeding
those generated during the milling process (>1500°C). This makes
them suitable for milling operations that may generate significant
heat and for samples that are temperature-sensitive.
- Ultra-Low Contamination: Introduces only negligible traces of
zirconium and yttrium oxides, which are often inert in most
chemical and material synthesis processes. This is the primary
advantage over alumina and stainless steel jars.
- High Fracture Toughness: Exceptional resistance to chipping and
impact, making them significantly more durable and longer-lasting
than alumina or agate jars.
2. Product Specifications & Range
Type: Planetary Ball Mill Jar (Vertical Cylindrical Design)
Capacity Range: 50ml, 100ml, 250ml, 500ml, 1L, 2L, 3L, 5L (Fully
customizable sizes within this range are available)
Sealing System: Hermetic seal with a clamped or screwed lid,
featuring a high-temperature silicone or Viton® O-ring. Options for
lids with gas inlet/outlet valves for inert atmosphere milling are
available.
Status: Laboratory Consumable. While incredibly durable, they are
designed for high-throughput labs and are considered a replaceable
component to ensure ongoing process integrity.
3. Key Advantages
- Unmatched Purity: Essential for research where any foreign element
contamination (Fe, Cr, Ni, Al) would compromise the material's
properties or analytical results. Ideal for battery materials,
pharmaceuticals, and advanced ceramics.
- Longest Service Life: The combination of extreme hardness and high
toughness ensures the longest operational lifespan of any jar
material, providing excellent value over time despite a higher
initial investment.
- Consistent Nano-Grinding Performance: Enables true and reproducible
nano-scale particle size reduction by preventing re-contamination
with larger wear debris.
- Versatile Application Range: Suitable for both high-energy
mechanical alloying and gentle mixing, across a wide temperature
spectrum.
4. Applications
These jars are critical consumables in advanced material research
and development:
- Battery Material Synthesis: Grinding of cathode (NMC, LFP) and
anode (silicon, graphite) materials where iron contamination is
catastrophic for performance.
- Pharmaceutical Nanoization: Size reduction of Active Pharmaceutical
Ingredients (APIs) to enhance bioavailability without metallic
impurities.
- Mechanical Alloying: Synthesis of novel metallic alloys and
composite materials from elemental powders.
- Advanced Ceramics Production: Processing of precursor powders for
technical ceramics (e.g., ZTA, silicon nitride).
- Pilot-Scale Production: Larger jars (2L-5L) are used to scale up
successful lab-scale processes.
5. Why Classify as a Consumable?
Even the most wear-resistant materials experience gradual
degradation over time. Classifying these jars as consumables
ensures:
- Process Consistency: Replacing jars at recommended intervals
guarantees that contamination levels remain consistently low and
that grinding efficiency does not diminish due to changes in jar
surface geometry.
- Data Integrity: For quality control and publication purposes, using
a jar with a known history prevents skewed results from a worn-out
vessel.
- Operational Safety: Proactive replacement mitigates the very low
risk of catastrophic failure after extensive use.
Summary
For laboratories where precision, purity, and performance are
non-negotiable, these high-purity zirconia planetary jars are not
just an accessory but an essential consumable. They provide the
foundation for reliable, contamination-free grinding and mixing,
enabling innovation in nanotechnology and advanced material
science.
Available from 50ml to 5L, they cover the entire spectrum of
laboratory needs, from initial R&D to pilot-scale production.
