Strontium phosphide is an inorganic compound of strontium and phosphorus with the chemical formula Sr
3P
2.[1][2] The compound looks like black crystalline material.[citation needed]
Synthesis
Heating strontium phosphate with soot in an arc furnace:
- Sr3(PO4)2 + 8 C → Sr3P2 + 8 CO
Reaction of strontium with red phosphorus at high temperature:[citation needed]
- 6 Sr + P4 → 2 Sr3P2
Physical properties
Strontium phosphide forms black crystals.[citation needed]
Thermally stable, melts at high temperatures.
Dangerous when wet, poison.[3]
Chemical properties
Decomposes with water releasing phosphine:[citation needed]
- Sr3P2 + 2 H2O → 3 Sr(OH)2 + 2 PH3
Reacts with acids:
- Sr3P2 + 6 HCl → 3 SrCl2 + 2 PH3
Uses
It is a highly reactive substance used as a reagent and in the manufacture of chemically reactive devices.[4]
