inorganic
Conclusions:
test done according to standard protocol, useful to assess the characteristic of the substance
Executive summary:

Appearance/physical state/colour of the substance was determined by visual inspection, odour by smell (organoleptic).

The physical state of the substance is solid powder, its colour is brown, it is odourless.

Description of key information

The physical state of the substance is solid powder, its colour is brown, it is odourless (Outotec, 2010).

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

Various types of leach residues were analyzed. They display differences in phys-chem. properties depending on their chemical composition. The most representative leach residue was used.
