Description of key information

Additional information

Appearance

Calcium fluoride is an odourless, colourless to white solid (powder or crystals) (Merck Index, GESTIS Substance database).

Melting point

The melting point of calcium fluoride is reported to be 1403 °C (Merck Index, GESTIS Substance database).

Boiling point

The boiling point of calcium fluoride is reported to be 2500 °C (Merck Index).

Density

The density of calcium fluoride is reported to be 3.18 g/cm³ (Merck Index, GESTIS Substance database, Gmelins (1957)).

Granulometry

Data are provided for a number of sources of calcium fluoride.

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 18 degrees Celsius (Merck Index).

Surface tension

A waiver is proposed for this data requirement. Based on chemical structure, no surface activity is predicted.

Flash point

No data are available. A waiver is proposed because 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 combustible solid and self-heating of the substance up to 400 °C is excluded.

Flammability

No data are available. A waiver is proposed for this data requirement as the substance is a non flammable and non combustible solid with a very high melting point (1403 °C). Based on chemical structure pyrophoric properties and flammability in contact with water are not to be expected.

Explosiveness

No data are available. A waiver is proposed for this endpoint because there are no chemical groups associated with explosive properties present in the molecule.

Oxidising properties

No data are available. A waiver is proposed for this endpoint because the substance 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 because the substance is an inorganic salt.

Viscosity

No data are available. A waiver is proposed for this data requirement because the substance is a solid at 20 °C and atmospheric pressure.
