Useful:

• Chemical Classes: Metals -> Phosphides
• Canonical SMILES: [P-3].[P-3].[Ca+2].[Ca+2].[Ca+2]
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. Inhalation of decomposition products may cause lung oedema. The substance may cause effects on the gastrointestinal tract, central nervous system, liver, kidneys and cardiovascular system. This may result in impaired functions and respiratory failure. Exposure could cause death.
• Description: Calcium phosphide has the molecular formula of Ca3P2 and the molecular weight of 182.1825 g/mol. Its CAS number is 1305-99-3. It is a red-brown crystalline material with a melting point of 1605°C. Its density is 2.51 g/cm3. It readily reacts with water to form phosphine, PH3, but is insoluble in ethanol. It is easily prepared by reacting the metal with red phosphorus at high temperature. The best way is to sublime the P4 at 450°C in an inert gas stream and react it with Mg metal at 750°C: 6Ca + 2P4?2Ca3P4
• Uses: For signal fires; in purification of Cu and Cu alloys; as rodenticide. Metal phosphides, primarily Ca3P2, have been used as rodenticides. Calcium phosphide baits have strong, pungent garlic-like odor characteristic for phosphine liberated by hydrolysis. The odor attracts rodents, but has a repulsive effect on other animals, who are not receptive to the smell. This salt has uses in incendiary bombs and other explosives. On contact with acids or water, calcium phosphide releases phosphine, which ignites spontaneously. It is also used in fireworks, torpedoes, self-igniting naval pyrotechnic flares, and various water-activated ammunition.
