Higher levels can cause weakness, bronchitis, pulmonary edema, shortness of breath, convulsions, and death. Some effects, such as pulmonary edema, convulsions, and liver injury, may appear or continue to be present days after an exposure. Ingestion of metal phosphides results in release of phosphine in your stomach which can cause nausea, vomiting, abdominal pain, and diarrhea. (L980) |

용도
개요
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 + 2P42Ca3P4
용도
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.
일반 설명
CALCIUM PHOSPHIDE appears as red-brown crystals to gray granular lumps. CALCIUM PHOSPHIDE reacts with water to form calcium hydroxide and phosphine, a flammable poisonous gas. Phosphine will normally ignite spontaneously in contact with air. If there is an excess of water this fire of phosphine will not normally ignite surrounding combustible material.
