- 23.4 °C
- Remarks on result:
- other: arithmetic mean of 5 determinations ± 15 kg/m³ standard deviation
- Conclusions:
- Under the described test conditions the test item, FeMo slag 1 (sadaci) (4-14 mm particle size), has a density of 2577 ± 15 kg/m³ at 23.4 °C.
Reference
Determinations were performed in five fold due to the heterogeneity of the test item. The CV (%) (coefficient of variation) is 0.6%.
Description of key information
The realtive density of the test item is 2.5.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.5
Additional information
A representative sample of ferromolybdenum slags from a major producer was subjected to an experimental test for relative density (pyknometer method). The density of this sample has been experimentally determined to be 2577 +/- 15 kg/m³ at 23.4 °C. Due to the production process and the heterogeneity of ferromolybdenum slags, the density of other samples may vary, but is expected to be in the range of ca. 2 to 3 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.
