zirconia planetary mill jar

A ceramic milling jar for applications where steel contact is undesirable.

Discuss this configuration Test your material

Overview

A ceramic milling jar for applications where steel contact is undesirable. Its selection should consider the proposed zirconia grade, liquid compatibility, jar dimensions and the sample’s contamination limits.

How it works

The jar working surface forms part of the contact system between sample, media and mill. Material selection should balance the required mechanical action with chemical compatibility and the acceptable contribution from wear.

Ceramic wear can still introduce zirconium-containing material. Zirconia is the ceramic oxide; it should not be confused with metallic zirconium.

Key features

Published dimensions include external diameter, internal diameter and height by nominal volume.
The jar is a ceramic component and needs protection from impact and thermal shock.
Jar and media materials should be selected together for the intended analysis.

Specifications

Published catalog references are reproduced below. Nominal volume is not a sample-mass rating. Confirm the selected model, material grade, electrical supply and complete supplied configuration in the quotation.

Applications

Ceramic, battery-material, pigment and other materials-development trials requiring evaluation of steel-free contact surfaces.

Suitability depends on the actual sample, process and analytical requirements; a listed application is not a guaranteed final-particle-size result.

Accessories and options

Specify volume, clamping envelope, lid/seal and the required ceramic grade. A material name alone does not confirm a vacuum rating.

State the required grade, quantities, drawings and destination when requesting a quotation. Confirm what is included, the document requirements, packing and commercial terms; no generic delivery time or universal custom capability is assumed.

Selection guidance

Match zirconia ceramic to the sample chemistry and the elements or residues that matter to the analysis. Then confirm the dimensions, complete loaded mass and operating arrangement against the selected mill.

The product information uses an unqualified zirconium-jar shorthand. It does not identify this jar part number or certify a zirconia grade. The exact XQM-0.4A model is recorded. No starting distribution or measurement method is supplied. D90 15.28 µm does not demonstrate that all particles were below the requested 10 µm limit.

How to plan a fair comparison

For a zirconia ceramic comparison, use matched sample portions and the same measurement/dispersion method. State the jar, media, mass/volume loading basis, processing schedule and contamination measurements. A change in material grade alone is not established as the cause of a result.

These anonymous records are not operating instructions. Measurement and dispersion methods are not fully specified in the test summaries; results apply to the reported samples and conditions.

Product FAQs

Does zirconia mean zero contamination?

No. It avoids a steel working surface, but wear and cross-contamination still need to be evaluated. Agree the relevant elemental limits and request material or batch documentation where required.

Which zirconia ceramic jar size will fit my mill?

Listed nominal volumes: 50mL, 100mL, 250mL, 500mL, 1L, 1.5L, 2L, 2.5L, 3L, 4L, 5L. Check external diameter, complete lid-inclusive height, holder/clamp geometry and loaded mass. Specify volume, clamping envelope, lid/seal and the required ceramic grade. A material name alone does not confirm a vacuum rating.

Can this jar be filled to its nominal volume with sample?

No. Allow space for media and material movement, and check the permitted loaded mass. Ceramic wear can still introduce zirconium-containing material. Zirconia is the ceramic oxide; it should not be confused with metallic zirconium. Agree the charge for the actual zirconia ceramic jar and process.

How should I choose the matching grinding media?

Consider the sample chemistry, the jar working material, contamination limits and the required result. Ceramic wear can still introduce zirconium-containing material. Zirconia is the ceramic oxide; it should not be confused with metallic zirconium. Confirm the complete pairing before specifying a diameter mix or media charge.

Can a custom size, lid or vacuum version be requested?

Specify volume, clamping envelope, lid/seal and the required ceramic grade. A material name alone does not confirm a vacuum rating. A proposed custom feature is subject to engineering confirmation and is not automatically included with a standard jar.

What trial evidence is available for this jar material?

Copper powder: XQM-0.4A, 51 g in 100 mL, 60 min. The product information uses an unqualified zirconium-jar shorthand. It does not identify this jar part number or certify a zirconia grade. The exact XQM-0.4A model is recorded. No starting distribution or measurement method is supplied. D90 15.28 µm does not demonstrate that all particles were below the requested 10 µm limit. A material-family observation does not certify the supplied part or grade.
