The recorded D50 of 3.64 µm was below the requested 8 µm fineness target.

A 7.8 g powder sample was dry-milled with zirconia media in a 250 mL jar at recorded speed setting 450. The measurement was taken at 30 minutes; the exact XQM model and particle-size measurement method were not specified.

The two-hour sample had D90 19.07 µm, below the recorded D90 fineness target of 50 µm.

The granular material was reduced in size before dry milling. The record identifies an XQM-0.4A, a 100 mL zirconia jar, zirconia media and a 155 g sample at speed setting 650. Media proportions are listed as large/medium/small 50/30/20; the proportion basis and measurement method are unspecified.

The recorded D50 of 3.69 µm lies within the requested 2–7 µm range. This is a particle-size result, not a catalytic-performance test.

A 300 g powder sample was dry-milled in the recorded omnidirectional QXQM configuration using a 500 mL alumina jar and zirconia media. The speed setting was 480; D50 and D90 were recorded after two hours. The exact mill capacity and particle-size measurement method were not specified.
