Description of key information
The particle size distribution of lithium bromide was measured in two studies using volumetric and counted distribution. The particle size distribution (volume distribution) of the test item produced the following values: d10: 7.99 µm, d50: 20.21 µm, d90: 38.27 µm. The particle size of the test item was determined by counted distribution and gave the following results: d10: 94.10-102.22 µm, d50: 188.87-198.90 µm, d90: 302.33-315.05 µm.
Additional information
The particle size distribution of lithium bromide was measured in two studies using volumetric (FMC, 2008) and counted (Chemetall, 2011) distribution. The particle size distribution (volume distribution) of the test item produced the following values: d10: 7.99 µm, d50: 20.21 µm, d90: 38.27 µm. (FMC, 2008)
The particle size of the test item was determined by counted distribution and gave the following results: d10: 94.10-102.22 µm, d50: 188.87-198.90 µm, d90: 302.33-315.05 µm. (Chemetall, 2011)
Differences of the results may depend on the technique of production and / or measurement of particle size distribution incl. sample preparation.
Consequently, for lithium bromide the percent of particles <10 µm is in the range of 0 - 20 % according to the available data.
