Conclusions:

The particle size distribution of the test item, lithium phosphate, was measured by laser diffraction. The results are as follows: D(10) = 0.79 µm, D(50) = 2.72 µm, D(90) = 8.49 µm.

Executive summary:

The particle size distribution of the test item, lithium phosphate, was measured by laser diffraction according to DIN EN ISO 9001. The results are as follows: D(10) = 0.79 µm, D(50) = 2.72 µm, D(90) = 8.49 µm. 13.60 % of the particles are ≤0.90 µm, 19.20 % are ≤ 1.10 µm and the fraction of particles ≤ 10 µm is 93.51 %.

Description of key information

The particle size distribution of the test item, lithium phosphate, was measured by laser diffraction according to EN ISO 9001 in two studies. At one study the values were as follows: D(10): 5.32 µm, D(50): 12.2 µm, D(90): 22.44 µm (FMC, 704.426.5300, 2012), at another study the values were as follows: D(10): 0.79 µm, D(50): 2.72 µm, D(90): 8.49 µm (Albemarle Germany, 2014).
