Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 273-729-7 | CAS number: 69012-29-9 By-product from the production of ferronickel from a complex ore. Consists primarily of oxides of aluminum, iron, magnesium and silicon.

Description of key information
Tests performed on the substance showed no flammability or oxidising properties. Additionally, the known constituents of the substance are not known to react violently in the presence of flame and oxidising agents. Its content of pyrophoric materials is also very low and this is supported by the granulometry of the material which is very coarse and unlikely to produce a dust explosion. Therefore, testing for the explosive properties of the substance is not necessary.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Explosivity can be defined as the tendency of a substance to undergo violent and rapid decomposition, under appropriate conditions, to produce heat and or gas. Whether or not a substance with explosive properties can cause an explosion depends on a number of factors. These include: the degree of confinement, the strength of the container it is in, the rate of heating, the nature of the initiation source, etc. (Guidance on information requirements and chemical safety assessment - Chapter R.7a: Endpoint specific guidance). Table R.7.1-28 of the guidance document provides a list of chemical groups that are known to contribute to explosivity.
According to Column 2 of REACH Annex VII (standard information requirements for substances manufactured or imported in quantities of 1 tonne per year or more) of Regulation (EC) No 1907/2006 a study to determine the explosiveness does not need to be conducted if there are no chemical groups associated with explosive properties present in the molecule.
Slags, ferronickel-manufg./ Electric Furnace Slag/ Converter Slag do not contain relevant functional groups known to contribute to explosivity.
Tests performed on the substance showed no flammability or oxidising properties (See endpoints 4.12, 4.13 and 4.15). Additionally, the known constituents of the substance are not known to react violently in the presence of flame and oxidising agents. Its content of pyrophoric materials is also very low and this is supported by the granulometry of the material which is very coarse and unlikely to produce a dust explosion. Therefore, testing for the explosive properties of the substance is not necessary.
Long-term experience in manufacturing, handling and use of Slags, ferronickel-manufg./ Electric Furnace Slag/ Converter Slag shows that are incapable to detonate. Taking into account the production process of Slags ( reduction by-products), it can be concluded that explosivity is not a concern for this substance. Hence a study on explosiveness is considered not to be necessary and is not required under Regulation (EC) No 1907/2006 (REACH).
Justification for classification or non-classification
Tests performed on the substance showed no flammability or oxidising properties.
It is concluded that Slags, ferronickel-manufg./Electric Furnace Slag/ Converter Slag are considered "not explosive" and do not have to be classified and have no obligatory labelling requirement for Explosiveness.
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.
