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.
