Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 266-045-5 | CAS number: 65997-16-2 High-Alumina cement is a mixture of chemical substances produced by burning or sintering at high temperature (greater than 1200°C (2192°F)) raw materials which are predominantly calcium carbonate, aluminium oxide, silica, and iron oxide. The chemical substances which are manufactured are confined in a crystalline mass. This category includes all of the chemical substances specified below when they are intentionally manufactured in the production of high-alumina cement. The primary members of this category are CaAl2O4, Ca4Al2Fe2O10, Ca12Al14O33, and Ca2SiO4. Other compounds listed below may also be included in the combination with these primary substances.@CaAl4O7@Ca2Al2SiO7@CaAl12O19@Ca4Al6SO16@Ca3Al2O6.@Ca12Al14Cl@CaO@Ca12Al14F2@Ca3SiO5@Ca6Al4Fe2.@Ca2Fe2O5.
PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According REACH annex XIII, persistence shall not apply to inorganic substances
In accordance with column 2 of REACH Annex IX the study does not need to be conducted as the substance has a low potential for bioaccumulation (moderate solubility in water and insoluble in fat) and direct and indirect exposure of the aquatic compartment is unlikely. The CAHC production has basically no waste material, as dust and off-specification products are recycled in the CAHC production process. Dust and powder being swept during cleaning will be recycled in the production.
Further has to be stated, that Aluminium is the most abundant metal in the Earth's crust, and the third most abundant element therein, after oxygen and silicon. It makes up about 8% by weight of the Earth's solid surface. Calcium is the fith most abundant element in the earth crust
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.
