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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Evidence connected to the experience in handling and use of the substance suggests that the substance does not show any non- self-ignition properties. Thus, it is expected to be an air-stable compound at room temperature over a prolonged period of time (days), without noticeable or undesirable reactions. Various studies on different apatites confirm the thermal stability of the substance up to very high temperatures (1200 °C). Melting point of synthetic apatites was reported as 1608-1670 °C. The substance is also not flammable.
In conclusion, a potential for spontaneous ignition is not expected: the substance can be considered as a non-pyrophoric and non-self-heating solid because it is not liable to self-heat by reaction with air and without energy supply.
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.
