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 (HP Type BM040): MMAD 39.93 µm GSD 2.28 µm
Barium carbonate fine powder (HP Type BM040): 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
