Description of key information
Appearance/physical state/colour
White phosphorus is described as a colourless to white, transparent, crystalline solid; it can also described as a yellow wax like solid. The substance is sometimes called yellow phosphorus; the yellow colour is due to the presence of impurities. There are two allotropic forms: alpha, forms cubic crystals and exists at room temperature; beta, forms hexagonal crystals.
Melting point
The melting point of the substance is 44.1 °C.
Boiling point
The boiling point of the substance is 280 °C.
Density
The density of the substance is 1.83 g/cm³ for the alpha form and 1.88 g/cm³ for the beta form.
Vapour pressure
The vapour pressure of the substance is 0.026 mmHg at 20 °C, and 0.181 mmHg at 44.1 °C (melting point).
Water solubility
The solubility of the substance in water is reported to be 0.33 mg/100 g water (3.3 mg/L) at 15 °C, and one part per 300,000 parts water.
Auto flammability
The auto ignition temperature of the test substance is 30 °C.
Additional information
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.
