Sample assessment
Chromium(III) oxide was prepared as a 1:1 powder-to-water charge. That dilution and the relatively low ball-to-powder ratio are part of the measured preparation. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Mill for 3 hours and record the resulting distribution.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical square planetary ball mill. The jar volume identifies the test container and does not establish an exact machine variant or production capacity. Equipment association follows the recorded machine designation.
Test setup
| Recorded planetary machine | XQM |
|---|---|
| Documented setup | 100 mL alumina jar; zirconia balls of 6 and 10 mm at recorded ball mass ratio 5:1; 24 g powder plus 24 g purified water; ball-to-powder ratio 1.3:1; speed setting 300. |
| Recorded operating cycle | Run 5 / pause 1; units not stated in mode field |
Speed values are reproduced as recorded settings. A rotational unit and planetary-disc versus jar-speed basis are not stated, so these numbers are not labelled rpm.
Recorded procedure and results
The powder-to-water mass ratio was 1:1. After 3 hours of wet planetary milling the sample measured D50 = 2.43 µm and D90 = 4.41 µm. Two additional materials are described as receiving the same requested processing, but the record supplies no identities or particle-size endpoints for them.
Interpretation
The supported result is the chromium-oxide distribution after the recorded wet treatment. It cannot establish the results for the unnamed additional materials or any improvement in a downstream coating or ceramic property.
Practical precautions
Retain the specified water and powder masses and distinguish the ball-size ratio from the ball-to-powder ratio. Use appropriate containment and assess wear contamination for the intended chromium-containing powder application.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For chromium(iii) oxide, a matched QXQM trial can test whether changing orientation affects this oxide slurry distribution at its recorded water ratio. Keep sample mass, media and sampling times controlled. This is a proposed comparison; the test record does not demonstrate a superior result for that alternative. Confirm jar compatibility and the permitted complete loaded mass before selecting a configuration.
Procedure records XQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
