What is strontium phosphide?
Description
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.
General Description
strontium phosphide is a solid which will evolve flammable and toxic gasses on contact with water. strontium phosphide is a highly reactive material used as a laboratory reagent and in the manufacture of chemically reactive devices.
Air & Water Reactions
Decomposed by water or moisture in air evolving toxic phosphine which often ignites.
Reactivity Profile
strontium phosphide is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides 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.
Health Hazard
Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
Fire Hazard
Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Containers may explode when heated. Runoff may create fire or explosion hazard.
