Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The particle size distribution (volume distribution) of lithium hydroxide anhydrous and monohydrate was measured by laser diffraction in two studies. The values in the first study for lithium hydroxide anhydrous were as follows: d10: 4 um, d50: 14 um, d90: 32 um in absence of ambient air and in the other study: d10: 190 um, d50: 391 um, d90: 631 um in presence of ambient air.
The values in the first study for lithium hydroxide monohydrate were as follows: d10: 202 um, d50: 440 um, d90: 570 um and in the other study: d10: 43 um, d50: 150 um, d90: 634 um.
Differences may depend on the technique of production and / or measurement of particle size distribution incl. sample preparation. Consequently for lithium hydroxide anhydrous the percentage of particles < 10 µm is in the range of 0.4 - 33 % and for lithium hydroxide monohydrate it is in the range of 1 - 1.5 %.
