Description of key information
Ferromolybdenum slags is an inorganic, compact, variable, typically greenish-grey to bluish solid.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Ferromolybdenum slags primarily consist of oxides of silicon, aluminium, calcium and iron, in a glass-like, mostly amorphous matrix. Ferromolybdenum slag solidifies from a reaction melt when the temperature drops below ca. 1100 - 1600 °C. The slag is crushed and granules or lumps with sizes ranging from a few millimetres to several centimeters are obtained. Slag grains can be mixed with sand, which may be used for lining the reaction vessel and which then adheres to the cooled slag.
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.
