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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Description of key information
Additional information
Appearance
Calcium fluoride is reported to have the form of a white powder or cubic crystals (Merck Index, CRC handbook)
Melting point
The melting point of calcium fluoride is reported to be 1403 °C (CRC Handbook, Arbetslivsinstitutet (2005)).
Boiling point
The boiling point of calcium fluoride is reported to be 2500 °C (CRC Handbook) and 2513 °C (Arbetslivsinstitutet, 2005).
Density
The density of calcium fluoride is reported to be 3.18 g/cm3 (CRC Handbook, Merck Index).
Granulometry
The particle size of the calcium fluoride powder depends on the production conditions. Several samples have been examined. The median diameter (D50) was found to be in the range of 6.16 - 583.22 µm.
Vapour pressure
A waiver is proposed for this data requirement as the melting point of calcium fluoride is above 300 °C.
Partition coefficient
A waiver is proposed for this data requirement as the substance is inorganic.
Water solubility
The water solubility of calcium fluoride is reported to be 15 mg/L at 15 degrees Celsius (Patty's) and 17 mg/L at 25 degrees Celsius (Merck Index).
Surface tension
A waiver is proposed for this data requirement. A study is not required as, based on a theoretical consideration of the structure, surface activity is not expected for the substance.
Flash point
No data are available. A waiver is proposed for this data requirement as the substance is an inorganic solid.
Autoflammability
No data are available. A waiver is proposed for this data requirement as the substance is a non-flammable inorganic solid. Based on a theoretical consideration of its chemical structure, autoflammability is not predicted.
Flammability
No data are available. A waiver is proposed for this data requirement as the substance is a non-flammable inorganic solid. Based on a theoretical consideration of its chemical structure, pyrophoric properties and flammability in contact with water are not predicted.
Explosiveness
No data are available. A waiver is proposed for this data requirement as the substance does not contain any chemical groups associated with explosive properties.
Oxidising properties
No data are available. A waiver is proposed for this data requirement as the substance does not contain any chemical groups associated with explosive properties and is incapable of reacting exothermically with combustible materials.
Stability in organic solvents
No data are available. A waiver is proposed for this endpoint as the substance is inorganic.
Dissociation constant
A waiver is proposed for this data requirement. The substance is an inorganic salt and will dissociate into its constituent ions in aqueous solution.
Viscosity
No data are available. A waiver is proposed for this data requirement as the substance is a solid.
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.
