Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 270-659-9 | CAS number: 68475-76-3 A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts. The following materials may also be present:@Dolomite@Ca(OH)2@Feldspars@CaSO4@Fly ash@KCl@Iron oxides@K2CO3@CaF2@K2SO4@CaO@Na2SO4@Glasses of SiO2, Al.s@Portland cement chemicals [659

Description of key information
The substance is not auto flammable, it shows no relative self-ignition below 400 °C.
Key value for chemical safety assessment
Additional information
The substance showed no relative self-ignition below 400 °C due to a study result acc. to EU A.16 testing method.
Even solid inorganic oxides in which the inorganic element is in its highest possible oxidation state are incapable of further reaction with oxygen and can thus be designated as non-flammable (ECHA Guidance on information requirements and chemical safety assessment Chapter R.7 a: Endpoint specific guidance, R.7.1.10.3). This is the case for most of the constituents.
The other inorganc constituents (non-oxides): KCl, NaCl are not flammable (according to data from handbooks).
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.
