Zirconia ceramic grinding jar

The zirconia ceramic grinding jar is made of high-purity yttrium stabilized zirconia (Y-TZP) material sintered at high temperature, which has excellent characteristics of high hardness, low wear, and resistance to strong acid and alkali corrosion. As the core component of planetary ball mills and drum ball mills, it not only ensures high energy efficiency in the grinding process, but also has extremely low pollutant precipitation, making it an ideal choice for high-purity materials and nanoscale grinding fields.

Product FAQ: Solving Your Core Grinding Difficulties
Q1: How to avoid sample cross contamination caused by tank wear when grinding high hardness materials such as silicon dioxide and tungsten carbide?
A: Our zirconia grinding jar has a Vickers hardness of ≥ 1200 HV and extremely low wear, which can effectively prevent heavy metals or heterogeneous detachment, ensure the purity of the chemical composition of the ground sample, and meet the requirements of spectral analysis or battery material synthesis.
Q2: Can suitable grinding tanks be matched for the existing planetary ball mills of different brands in the laboratory?
A: We provide customized services based on images. Whether it is German RETSCH, American SPEX or domestic equipment, precise matching can be carried out according to equipment model, pitch and installation size to ensure sealing and dynamic balance.
Q3: How to prevent the tank from being corroded and leaking when using organic solvents or strong acids in wet grinding?
A: Zirconia materials have strong chemical inertness and are resistant to strong acids and bases. At the same time, we have equipped corrosion-resistant PTFE or fluororubber sealing rings to ensure that the slurry does not leak out during high-speed operation, solving the problems of corrosion and leakage.

Product Core Advantage: Why Choose Zirconia Material

1. Excellent mechanical performance
   -Ultra high hardness and density: The product density can reach 6.02-6.05 g/cm ³, second only to diamond in hardness, giving the grinding tank extremely strong wear resistance, and the service life is several times that of stainless steel tanks or ordinary corundum tanks.
   -High toughness: Zirconia has phase transition toughening properties, strong impact resistance, and is not easily broken. It can withstand the huge impact energy caused by the high-speed operation of planetary ball mills.
2. Zero pollution grinding guarantee
   -Low wear: Due to its high hardness, the inner wall of the tank body hardly falls off during the grinding process, eliminating trace pollution to the grinding materials (such as catalysts and rare earth materials) from the root.
   -High purity: Made from 95% or 99% yttrium stabilized zirconia raw material, with extremely low impurity content, ensuring no color change when grinding white or light colored materials.
3. Widely applicable fields
   -Materials Science: Grinding of ceramic powders (silicon nitride, boron carbide) and hard alloys.
   -New energy: nanoscale dispersion of positive and negative electrode materials (lithium iron phosphate, lithium cobalt oxide) for lithium batteries.
   -Biopharmaceuticals: Grinding of high-purity active ingredients to avoid the introduction of metal ions.
   -Geological and Mineral Resources: Non polluting Sample Preparation for XRF Fluorescence Analysis.

Specifications and customized services: meet your precise needs
We are well aware that “standard products” are difficult to adapt to all processes, so we provide highly flexible customized solutions:
-Standard specification inventory: Available in regular capacities such as 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml (1L), 1.5L, 2L, 3L, 5L, etc., supporting single can or complete set (including lid and sealing ring) shipment.
-Non standard customization (ODM/OEM):
-Size customization: Customize tank bodies with special heights, wall thicknesses, or interface shapes based on user provided drawings or physical objects.
-Structural customization: It is possible to add baffles or change the shape of the inner wall to optimize grinding efficiency.

Customer Application Cases
Case: A well-known new material technology company (anonymous)
-Customer requirement: The customer needs to grind the silicon carbide powder to D50<1 micron. The original stainless steel tank was found to be heavily contaminated with iron (increasing by about 200ppm), resulting in a decrease in downstream semiconductor grade application yield.
-Solution: We provided it with a 5L high-capacity high-purity zirconia ceramic grinding tank and matched it with the corresponding zirconia grinding medium. In response to the high rotational speed of its planetary grinding machine, the threaded structure of the tank mouth and the thickened sealing gasket have been specially reinforced.
-Final effect:
-Purity improvement: Through ICP-MS detection, heavy metal pollution such as iron has been reduced from 200ppm to below 10ppm, fully meeting electronic grade material standards.
-Efficiency optimization: Due to the extremely smooth and dense inner wall of the zirconia tank, the grinding efficiency has been improved by 20%, and the one-time fineness has reached 0.8 microns.
-Durability: After continuous use for 6 months, there are no obvious scratches on the inner wall of the tank, and the wear is almost zero, solving the pain point of frequent tank replacement for customers.
