2.4 Material properties of candidate RMs
The powder obtained were characterised fortheir particle size distribution by laser diffraction using a Helos laser light scattering instrumentZsympatec GmbH System-Partikel-Technik, Clausthal-Zellerfeld, DE) The residual water content was determined using volumetric Karl-Fischer titration as described previously
Analyses were performed on three randomly-picked samples from each material in triplicate.
