8.7 % of the particles < 1.80 µm

15.73 % of the particles < 3 µm

43.96 % of the particles < 10 µm

Conclusions:
The particle size distribution of the test item, lithium nitride, was measured by laser diffraction. The results are as follows: D(10) = 2.01 µm, D(50) = 12.53 µm, D(90) = 59.66 µm.
Executive summary:

The particle size distribution of the test item, lithium nitride, was measured by laser diffraction equivalent or similar to ISO 13320. The results are as follows: D(10) = 2.01 µm, D(50) = 12.53 µm, D(90) = 59.66 µm. 8.7 % of the particles are ≤1.8 µm, 15.73 % are ≤ 3 µm and the fraction of particles ≤ 10 µm is 43.96 %.

Additional information

The particle size distribution of the test item, lithium nitride, was measured by laser diffraction equivalent or similar to ISO 13320 (Albemarle, 2016). The results are as follows: D(10) = 2.01 µm, D(50) = 12.53 µm, D(90) = 59.66 µm. 8.7 % of the particles are ≤1.8 µm, 15.73 % are ≤ 3 µm and the fraction of particles ≤ 10 µm is 43.96 %.
