Strontium phosphide (Sr3P2)

説明Strontium phosphide has the molecular formula of Sr3P2 and the molecular weight of 324.8075 g/mol. Its CAS number is 12504-13-1. It is a black crystalline material with a melting point of 1205°C. Its density is 2.71 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 Sr metal at 650°C: 6Sr + 2P4 2Sr3P4 Strontium phosphide is a solid which will evolve flammable and toxic gases on contact with water. It also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.
