Description of key information
Three density values have been identified for titanium hydride. Two of them are handbook data. These values are 3.752 g/cm3 (Knovel Sampler) and 3.91 g/cm3 (Knovel Critical Tables - 2nd Edition). The third density value is internal Company data (bulk density) of 2 500.00 kg/m3. Therefore, the density value for TiH2 ranged between 2.5 g/m3 (bulk data ) to 3.91 g/cm3.
Key value for chemical safety assessment
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.
