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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 melting point range is between 1050 °C and 1200 °C (OECD 102).
Key value for chemical safety assessment
Additional information
The value of the melting range is based on the measurements of the sample P.1034, which is taken from the plant of Holcim in Dotternhausen (Germany). The additional endothermic peaks of the SDTA signal are associated with the decomposition of portlandite/lime (between 400 °C and 500 °C) as well as decomposition of carbonates (between 700 °C and 800 °C).
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.
