Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

particle size distribution (granulometry)
Type of information:
other: Internal data
SAP extract
Adequacy of study:
key study
1 (reliable without restriction)
equivalent or similar to guideline
ISO 13320 (Particle size analysis - Laser diffraction methods)
Version / remarks:
Internal Company method
Principles of method if other than guideline:
- Basic principle
This method of measurement is based on the interaction between light beams and solid particles. Under the assumption of spherical particles, a laser diffraction pattern can be used to deduce the particle size distribution within a sample.

- Apparatus
Cilas granulometer
Measuring range: 0.04-2500 μm

- Procedure
The sample is suspended in a suitable liquid, if necessary, under the addition of a dispersion agent. The suspension is homogenized by stirring and treatment with ultrasound and subsequently pumped through a cuvette. The cuvette is simultaneously radiated by a helium-neon-laser. The light diffraction pattern resulting from the interaction of laser beam and solid particles is detected by a photomultiplier and converted into a particle size distribution by a processor unit.
Type of method:
Laser scattering/diffraction
Key result
ca. 3.662 µm
Remarks on result:
other: SAP extract
The granulometry of TiH2 has been determined using Laser diffraction (Internal Company method). D50 was 3.662 µm (mean value).
