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
Flue dust is a powdery inorganic material. The colour can vary between beige and grey, depending on the composition (UVC substance).
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Flue dust is a UVC substance, whose constituents are minerals and therefore inorganic solids at room temperature.
The evaluation of this endpoint based on a study which has been done using appropriate test methods, in compliance with ISO 17025. The study was performed with a sample representative of the substance to be registered: "Flue Dust T (REACH)"
