Product: Customized Zirconia Ball Mill Jars (50ml - 300ml)
This offering is for high-quality, custom-manufactured zirconia
grinding jars designed for planetary ball mills, perfectly suited
for a wide range of laboratory experiments.
1. Core Material: "95 Zirconium" Explained
The term "95 Zirconium" typically refers to a material that is 95%
ZrO₂ (Zirconia) by mass, with the remaining ~5% being a stabilizer
(almost always Yttria - Y₂O₃).
What it is: This is a specific grade of Yttria-Stabilized Zirconia
(YSZ). The yttria is not an impurity; it is a critical additive
that stabilizes the zirconia's crystal structure, giving it the
renowned toughness and strength.
Why it's Excellent for Jars:
- High Fracture Toughness: Resists chipping and cracking from the
high-impact forces in a planetary ball mill.
- Superior Wear Resistance: Much harder and more wear-resistant than
alumina, ensuring a long jar life and minimal contamination.
- Chemical Inertness: Will not react with most chemical samples,
ensuring a contamination-free grinding environment.
2. Size Range: 50ml to 300ml
This covers the most popular sizes for bench-scale laboratory
research.
- 50ml & 100ml Jars: Ideal for small-batch experiments, precious or
expensive materials, and initial feasibility studies where sample
quantity is limited.
- 250ml & 300ml Jars: Perfect for standard lab work, providing a good
balance between sample volume and grinding efficiency. This is
often the go-to size for many R&D processes.
3. The "Customized" Aspect
This is the key value proposition. Customization can include:
- Lid Design:
- Standard Sealed Lid: With a robust rubber O-ring for general use.
- Gas-Purging Lid: Features a valve to allow the jar to be evacuated
and filled with an inert gas (like Argon or Nitrogen). This is
critical for grinding materials that are sensitive to air or
moisture (e.g., battery materials).
- Internal/External Finishing:
- Standard Finish: Suitable for most applications.
- Mirror Polished Interior: Essential for nano-scale grinding and
applications where cross-contamination or ease of cleaning is a top
priority.
- Physical Configuration: Jars can be customized to ensure a perfect
fit and optimal performance on specific planetary ball mill models
(from brands like Retsch, Fritsch, Guangzhou Zoli, or other
QM-series mills).
Application: Planetary Ball Mill Experiments
These jars are the core component where the actual processing
happens in a planetary ball mill. The experiments they are used for
include:
- Mechanical Alloying: Solid-state powder processing to create
alloyed materials from elemental powders.
- Size Reduction/Nano-Grinding: Breaking down agglomerates and
primary particles to achieve fine and nano-sized powders for
enhanced reactivity or specific properties.
- Mixing and Homogenization: Creating perfectly uniform mixtures of
different powder materials (e.g., ceramic composites).
- Cell Disruption: In biological labs, for breaking down plant or
microbial cells to extract contents.
- Process Emulation: Testing how materials will behave under
mechanical stress on a small scale.
Summary of Value Proposition
By offering customized 95% ZrO₂ jars in the 50ml-300ml range, the
supplier provides researchers with:
- Precision & Control: Tailored to their exact experimental needs
(atmosphere, size, finish).
- Purity & Integrity: Zirconia ensures their samples remain
uncontaminated by the grinding media.
- Durability & Cost-Effectiveness: The jars withstand long experiment
runtimes and repeated use, offering a better long-term value than
less durable materials.
- Optimized Performance: A perfect fit for their mill and purpose
leads to more reliable and reproducible experimental results.
