Description of key information

In a GLP study the particle size distribution was assessed as the d(0.1), d(0.5) and d(0.9) percentiles of 370 µm, 590 µm and 880 µm respectively, using a particle size apparatus based on laser diffraction (Sydney P, 2013). 

Additional information

Barium nitrate was determined to have d(0.1), d(0.5) and d(0.9) values of 370, 590 and 880 µm respectively.
