Description of key information

Under the conditions of this study the average size of the particles was determined to be 28.31 µm.

Additional information

The key study was assigned a reliability score of 2 in accordance with the criteria for assessing data quality defined in Klimisch (1997).

The granulometric content of the test material was evaluated using a laser diffraction particle size analyser, Microtrac S3000. 

A sample of the test material was dispersed into de-ionised water and processed ultrasonically; the suspension was then re-circulated and settled by three laser beams. The laser beams were dispersed by the particles and collected with multi-elemental detectors for analysis.

Under the conditions of this study the average size of the particles was determined to be 28.31 µm.
