Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Available data for lithium sulfate anhydrous:
(1) The particle size distribution of the test item lithium sulfate anhydrous was measured by volumetric distribution.
The values were as follows: d10: 11.11 µm, d50: 88.86 µm, d90: 158.76 µm.
(2) The particle size distribution of the test item lithium sulfate was measured by counted distribution.
The values were as follows: d10: 0.91- 0.95 µm, d50: 4.56- 5.00 µm, d90: 20.02 - 21.64 µm.
Available data for lithium sulfate monohydrate:
The particle size distribution of the test item lithium sulfate monohydrate was measured by volumetric distribution.
The values were as follows: d10: 33.23 µm, d50: 212.71 µm, d90: 485.92 µm.
Additional information
The particle size distribution of lithium sulfate and its monohydrate was measured in three studies using volumetric and counted distribution.
The particle size distribution (volume distribution) of the two test items produced the following values:
anhydrous: d10: 11.11 µm, d50: 88.86 µm, d90: 158.76 µm
monohydrate: d10: 33.32 µm, d50: 212.71 µm, d90: 485.92 µm (FMC, 2010)
The particle size distribution of lithium sulfate anhydrous by counted distribution gave the following results:
d10: 0.91 -0.95 µm, d50: 4.56 -5.00 µm, d90: 20.02 -21.64 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 sulfate anhydrous the percentae of particles <10 µm is in the range of 0 - 20 % according to the available study data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
