Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two key density values were retained. The first one is an average density of 5.72 g/cm3 for a series of samples with CaO content between 3.7 and 4.8% w/w and varying particle size distributions (Börger and Kurz, 2014), whereas the other is a value of 5.49 g/cm3 for a sample with 10% CaO w/w (Börger, 2015).
Key value for chemical safety assessment
Additional information
The results of two key studies, both applying the pycnometer method, were retained (Börger and Kurz, 2014; Börger, 2015). The first study measured the density of six samples with CaO content varying between 3.7 and 4.8% w/w and varying particle size distribution. The average density of these samples was 5.72 g/cm3. The second study measured the density of a sample with 10% CaO w/w and reported a density of 5.49 g/cm3.
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.
