Description of key information

Barium carbonate standard: MMAD 24.22 µm GSD 4.87 µm
Barium carbonate standard: D50 2.32 µm (Laser diffraction)
Barium carbonate fine powder: MMAD 39.93 µm GSD 2.28 µm
Barium carbonate fine powder: D50 14.6 µm (Laser diffraction)

Additional information

The reason of the high D50 value of barium carbonate fine powder in relation to the standard powder of barium carbonate is (i) that the measurement was performed without previous suspension in a solvent (ii) and the substance agglomerates.
