Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- relative density
- Density:
- ca. 2.073
- Temp.:
- 19.1 °C
- Remarks on result:
- other: Mean value of two assays (assay No.1: 2.074 ± 0.001, assay No.2: 2.072 ± 0.002).
- Conclusions:
- The relative density of yttrium trichloride hexahydrate was determined according to the EU A.3 method and OECD test guideline 109 in compliance with GLP using a gas comparison pycnometer. The relative density of the test item was determined to be 2.073 ± 0.002 at 19.1°C.
Reference
Two independent measurements were performed at 19.1°C.
The two assays resulted in relative densities of 2.074 ± 0.001 and 2.072 ± 0.002, respectively. The mean relative density was thus 2.073 ± 0.002 at 19.1°C.
Reference volume (Va) was 79.444 cm³.
Volume of sample cell holder (Vc) was 27.678 cm3.
Test item sample weight was 5.9608 g and 6.3448 g in assay No. 1 and 2, respectively.
The measurements are described in the table in the next section.
Description of key information
A guideline study (Demangel, 2017; Klimisch 1) to establish the relative density of the test item (yttrium trichloride hexahydrate) was performed according to the EU A.3 method and OECD test guideline 109 in compliance with GLP using a gas comparison pycnometer. The relative density of the test item was determined to be 2.073 ± 0.002 at 19.1°C. Results of this study are reliable without restrictions.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.073
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
