Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 297-648-1 | CAS number: 93685-99-5 Oil shale waste is produced by thermal processing in a fluidized bed process at 800°C from mining exhausted oil shale. Oil shale waste consists essentially of Al2O3, CaO, CaSO4, Fe2O3 and SiO2.

Description of key information
The particle size distribution of sample P.1034 and P.1082 determined by means of Laser-Diffraction (Laser-Granulometer, liquid dispersion):
d10 = 0.8 µm (gBOS P.1034); 0.6 µm (gBOS P.1082);
d50 = 9.4 µm (gBOS P.1034); 6.5 µm (gBOS P.1082);
d90 = 49.1 µm (gBOS P.1034); 41.6 µm (gBOS P.1082);
The particle size distribution of sample P.1125 and P.1183 determined by means of sieving analysis:
d10 = 2200 µm (gBOS P.1125); 2200 µm (gBOS P.1183);
d50 = 3300 µm (gBOS P.1125); 4000 µm (gBOS P.1183);
d90 = 5000 µm (gBOS P.1125); 5900 µm (gBOS P.1183).
Additional information
The samples (P.1034 and P.1082) taken from the plant of Holcim in Dotternhausen (Germany) are fine powders. Therefore the particle size distribution of these two samples were determined by using laser-diffraction method. The particle size is in the range of 0.3 to 90 µm. The PM4 (alveolar fraction, 4 µm or smaller) accounts for 33.4% and 39.1% of the P.1034 and P.1082 particles, respectively.
The samples (P.1125 and P.1183) taken from the plant of ICL Fertilizer Europe C.V. in Arava (Israel) are in granular forms. So the particle size distribution of these two samples were measured by using automated sieving method. The particle size is in the range from 0.125 to 8.0 mm.
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.
