Professional Zirconia Ball Mill Grinding Jars for Planetary Ball Mills

Overview:
Our premium Yttria-Stabilized Zirconia (YSZ) ball mill jars are engineered for the most demanding laboratory and research applications. Designed specifically for use in planetary ball mills, these jars offer unparalleled grinding efficiency, extreme durability, and minimal contamination. They are the ideal choice for high-energy milling where sample purity, mechanical strength, and wear resistance are paramount.

Key Features & Benefits:

1. Ultra-High Purity & Contamination-Free Grinding (95% ZrO₂):

   • Material: Manufactured from 95% Zirconium Oxide (ZrO₂), stabilized with Yttria. This high zirconia content ensures that the jar itself is exceptionally hard and contributes virtually no contaminants to your sample. This is critical for applications like ceramics, pharmaceuticals, electronics, and geology where even trace amounts of metal impurities (from stainless steel jars) can skew results.

   • Superior Hardness: Zirconia is one of the hardest ceramic materials available, significantly harder than alumina. This translates to faster size reduction and the ability to process hard, abrasive materials like quartz, minerals, and advanced composites.

2. Exceptional Wear & Impact Resistance:

   • Zirconia's remarkable fracture toughness and resistance to mechanical shock make these jars highly resistant to cracking and chipping, even under the high-impact forces generated in planetary ball mills. They offer a much longer service life compared to other ceramic jars.

3. Excellent Chemical Inertness:

   • Zirconia is highly resistant to acids, alkalis, and solvents. This inertness allows for wet grinding using a wide range of grinding media (e.g., zirconia balls themselves for ultimate purity, or alumina) and various solvents without risk of corrosion or chemical reaction with the jar material.

4. Precision Engineering & Secure Sealing:

   • Custom Sizes: Available in a comprehensive range of standard and custom volumes, from 50ml for precious, small-batch experiments up to 3000ml for larger-scale production or processing.

   • Leak-Proof Design: Features a precision-machined lid with a robust silicone O-ring gasket. This creates a completely sealed environment, preventing leakage, evaporation, and atmospheric exposure, which is essential for grinding in inert gas or preventing oxidation.

   • Secure Clamping System: The jar design is compatible with standard planetary mill clamping mechanisms, ensuring the jar remains firmly locked in place during high-speed rotation.

5. Smooth Inner Surface:

   • The interior is polished to a smooth finish to minimize dead zones where material can get stuck, promoting better mixing and easier cleaning post-experiment.
